1.  catena-Poly[[cadmium-bis­(μ-triethyl­ene­tetra­mine-κ4 N,N′:N′′,N′′′)-cadmium-(μ-triethyl­ene­tetra­mine-κ4 N,N′:N′′,N′′′)] hexa­fluoridogermanate] 
The title fluoridogermanate, {[Cd2(C6H18N4)3][GeF6]}n, was synthesized hydro­thermally. The crystal structure comprises undulated cationic [Cd2(TETA)3]4+ chains (TETA is triethyl­ene­tetra­mine) propagating parallel to [101]. The central CdII atom is six-coordinated in a CdN6 set by three TETA ligands. The isolated [GeF6]2− units, serving as counter-anions, occupy the inter-chain spaces and simultaneously link adjacent chains into a three-dimensional network through extensive N—H⋯F hydrogen-bonding inter­actions. One of the ethyl­ene bridges of one TETA ligand is disordered around a twofold rotation axis.

2.  Bis[tris­(ethyl­enediamine-κ2 N,N′)cobalt(III)] octa­kis-μ-3-oxido-hexa­deca-μ2-oxido-tetra­deca­oxido-μ12-tetra­oxo­silicato-octa­molybdenum(VI)hexa­vanadium(IV,V) hexa­hydrate 
The title compound, [Co(C2H8N2)3]2[SiMo8V4O40(VO)2]·6H2O, was prepared under hydro­thermal conditions. The asymmetric unit consists of a transition metal complex [Co(en)3]3+ cation (en is ethyl­enediamine), one half of an [SiMo8V4O40(VO)2]6− heteropolyanion, two solvent water mol­ecules in general positions and two half-mol­ecules of water located on a mirror plane. In the complex cation, the Co3+ ion is in a distorted octa­hedral coordination environment formed by six N atoms of the three chelating en ligands. One of the en ligands exhibits disorder of its aliphatic chain over two sets of sites of equal occupancy. The [SiMo8V4O40(VO)2]6− heteropolyanion is a four-electron reduced bivanadyl-capped α-Keggin-type molybdenum–vanadium–oxide cluster. In the crystal, it is located on a mirror plane, which results in disorder of the central tetra­hedral SiO4 group: the O atoms of this group occupy two sets of sites related by a mirror plane. Furthermore, all of the eight μ2-oxide groups are also disordered over two sets of sites with equal occupancy. There are extensive inter­molecular N—H⋯O hydrogen bonds between the complex cations and inorganic polyoxidoanions, leading to a three-dimensional supra­molecular network.

3.  Tris(ethyl­enediamine)manganese(II) sulfate 
In the title compound, [Mn(C2H8N2)3]SO4, the metal atom (site symmetry 3.2) is coordinated by six N atoms from three ethyl­enediamine (en) ligands in a slightly distorted octa­hedral geometry. The en ligands are generated from one half-mol­ecule in the asymmetric unit. The O atoms of the sulfate anion (S site symmetry 3.2) are disordered over four orientations in a 0.220 (12):0.210 (13):0.203 (14):0.10 (2) ratio, with one of the O atoms having site symmetry 3. In the crystal, the ions are connected by N—H⋯O hydrogen bonds, forming a three-dimensional network.

4.  Tris(ethyl­enediamine)zinc(II) hexa­fluorido­silicate 
The title compound, [Zn(C2H8N2)3](SiF6), was synthesized ionothermally using choline chloride–imidazolidone as solvent and template provider. In the crystal structure, the anions and cations are located on special positions of site symmetry 3.2 and show a typical octa­hedral geometry. The ZnII ion is coordinated by six N atoms from three ethyl­enediamine mol­ecules. The crystal structure displays weak hydrogen bonding between [SiF6]2− anions and the ethyl­enediamine NH hydrogen atoms.

5.  μ3-Dodeca­tungsto(V,VI)aluminato-κ3 O:O′:O′′-tris­[aqua­bis­(ethyl­ene­diamine-κ2 N,N′)copper(II)] 
The title compound, [AlCu3W12O40(C2H8N2)6(H2O)3], was prepared under hydro­thermal conditions. The Cu2+ ion displays an elongated octa­hedral geometry defined by one bridging O atom from the polyoxidoanion and a coordinated water mol­ecule in axial positions and four N atoms of the two chelating ethyl­enediamine (en) ligands in equatorial positions. The one-electron reduced [AlW12O40]6− anion coordinates three [Cu(en)(H2O)]2+ fragments, generating a neutral tri-supported Keggin-type polyoxidometalate (POM). This tri-supported POM is located in a special position of symmetry and therefore O atoms from the central AlO4 tetra­hedron are disordered over two sets of sites. Disorder is also observed for three other bridging O atoms of the POM. In the crystal, mol­ecules are connected via N—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional framework.

The crystal structure of the title compound, [Cd2Cl2(C2H8N2)4]Cl2, consists of binuclear centrosymmetric [Cd2(C2H8N2)4Cl2]2+ cations and discrete chloride anions. The CdII cation is coordinated by four N atoms of two ethyl­enediamine ligands and two symmetry-related chloride anions within a distorted CdN4Cl2 octa­hedron. Two CdII cations are connected by two chloride anions via μ2-coordination, forming a four-membered Cd2Cl2 ring. The uncoordinated chloride anions are linked to the amino groups via N—H⋯Cl hydrogen bonding. Two C atoms of one of the two crystallographically independent ethyl­enediamine ligands are disordered and were refined using a split model [occupancy ratio 0.674 (9):0.326 (9)].

7.  Diaqua­bis(ethyl­enediamine-κ2 N,N′)copper(II) 2,2′-dithio­dinicotinate sesquihydrate 
In the title compound, [Cu(C2H8N2)2](C12H6N2O4S2)·1.5H2O, there are two half-molecules of the cationic complex in the asymmetric unit. The Cu2+ ions lie on inversion centres and are octa­hedrally coordinated by two ethyl­enediamine (en) and two aqua ligands in a typical Jahn–Teller distorted environment with the water O atoms in the axial positions. Two 2-mercaptonicotinate units (mnic) are linked by a disulfide bridge. All the ethyl­enediamine N—H and O—H groups form inter­molecular hydrogen bonds with acceptor O and N atoms, giving rise to a three-dimensional network. One of the uncoordinated water molecules has a site occupation factor of 0.5.

8.  catena-Poly[[triaqua­cadmium(II)]-μ-pyridine-2,3-dicarboxyl­ato-κ3 N,O 2:O 3] 
The title polymeric compound, [Cd(C7H3NO4)(H2O)3]n or [Cd(py-2,3-dc)(H2O)3]n, where py-2,3-dcH2 is pyridine-2,3-dicarboxylic acid, was obtained by the reaction of cadmium(II) nitrate hexa­hydrate with (pipzH2)(py-2,3-dc) as a proton-transfer compound in aqueous solution (pipz is piperazine). The mol­ecular structure shows that only the anionic fragment of the starting proton-transfer compound is present in the complex, while the (pipzH2)2+ dication has been lost. Each (py-2,3-dc)2− ligand bridges two CdII atoms in two different coordination modes, i.e. one end acts as a monodentate and the other end as a bidentate ligand. The three remaining coordination sites on the metal center are occupied by water mol­ecules. The geometric arrangement of the six donor atoms around the CdII atom is distorted octa­hedral. In the crystal structure, O—H⋯O and C—H⋯O hydrogen bonds play an important role in stabilizing the supra­molecular structure.

The structure of the title compound, [CoII(C2H8N2)3]SO4, the cobalt example of [M(C2H8N2)3]SO4, is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively. The Co atom is coordinated by six N atoms of three chelating ethyl­enediamine mol­ecules generated from half of the ethyl­enediamine mol­ecule in the asymmetric unit. The O atoms of the sulfate anion are disordered mostly over two crystallographic sites. The third disorder site of O (site symmetry 3) has a site occupancy approaching zero. The H atoms of the ethyl­enediamine mol­ecules inter­act with the sulfate anions via inter­molecular N—H⋯O hydrogen-bonding inter­actions.

The Co ion in the title salt, [Co(NO3)(H2NCH2CH2NH2)2](OH)(NO3), has oxidation state + III and is coordinated by four N atoms from two ethyl­enediamine mol­ecules and two O atoms from a nitrate anion in a distorted octa­hedral geometry. The charge of the complex cation is balanced by a hydroxide anion and a nitrate anion. The cations and anions are connected by N—H⋯O and O—H⋯O hydrogen bonds, resulting in a three-dimensional supra­molecular framework. There are two independent ion pairs with similar configurations in the unit cell. Both uncoordinated nitrate counter-anions are disordered.

The asymmetric unit of the title complex, [Cu(C2H8N2)2(H2O)2](C8H8NO2)2·2H2O, contains one anion, one half-cation and one water mol­ecule. The CuII atom in the [Cu(en)2(H2O)2]2+ cation (en is ethyl­enediamine) lies on an inversion centre. The four N atoms of the en ligands in the equatorial plane around the CuII atom form a slightly distorted square-planar arrangement, while the slightly distorted Jahn–Teller octa­hedral coordination is completed by two water O atoms in axial positions. In the crystal structure, intra- and inter­molecular N—H⋯O and O—H⋯O hydrogen bonds form a three-dimensional network.

16.  Poly[[(1,10-phenanthroline){μ3-2,2′,2′′-[1,3,5-triazine-2,4,6-triyltris(sulfane­diyl)]triacetato}­cadmium] 0.42-hydrate] 
The asymmetric unit of the title complex, {[Cd(C9H7N3O6S3)(C12H8N2)]·0.42H2O}n, contains a CdII atom, one doubly deprotonated 2,2′,2′′-[1,3,5-triazine-2,4,6-triyltris(sulfanediyl)]triacetic acid ligand (HTTTA2−), a 1,10-phenanthroline (phen) ligand and a fractionally occupied water mol­ecule [site occupancy = 0.421 (15)]. The CdII atom is six-coordinated within a distorted octa­hedral coordination geometry. Six coordination arises from four O atoms derived from three different HTTTA2− ligands, and two N atoms of the chelating phen mol­ecule. The incompletely deprotonated triazine ligand adopts a μ3-η1:η1:η2 coordination mode, resulting in the formation of chains along the c axis based on Cd2O2 dimeric units. Adjacent chains are stacked through π–π stacking [3.533 (2) Å between phen and triazine rings] and C—H⋯O inter­actions, forming supra­molecular sheets in the ab plane. Intra-and intermolecular O—H⋯O hydrogen bonds are also observed.

17.  Ethyl­enedi­ammonium sodium tetra­kis­[bis­(ethyl­enedi­amine-κ2 N,N′)(oxalato-κ2 O 1,O 2)cobalt(III)] [penta­hydrogen di(phosphato­octa­deca­tungstate)] tetra­deca­hydrate 
The title compound, Na(C2H10N2)[Co(C2O4)(C2H8N2)2]4[H5(P2W18O62)2]·14H2O, prepared under hydro­thermal conditions, consists of two Dawson-type [P2W18O62]6− anions, four isolated [Co(en)2(ox)]+ cations (en = ethyl­enedi­amine and ox = oxalate), one Na+ cation, one [H2en]2+ cation, and a number of ordered (14) and disordered solvent water mol­ecules. The [P2W18O62]6− polyoxidometalate anion has site symmetry 1 and contains two structurally distinct types of W atoms: viz. six W atoms on vertical pseudo-mirror planes grouped in two sets of three, and 12 equatorial W atoms that do not lie in the pseudo-mirror planes grouped in two sets of six. In each [Co(en)2(ox)]+ cation, the CoIII ion is coordinated by four N atoms from two en ligands and two O atoms from the ox ligands, completing a distorted octa­hedral structure. The sodium cation lies on an inversion centre and additionally links the complex cations and anions. In the crystal, the various units are linked by N—H⋯O and O—H⋯O hydrogen bonds, which together with C—H⋯O hydrogen bonds form a three-dimensional structure. The contribution of a region of disordered electron density, possibly highly disordered solvent water mol­ecules, to the scattering was removed with the SQUEEZE option of PLATON [Spek (2009 ▶). Acta Cryst. D65, 148–155]. To equilibrate the charges five H+ ions have been added to the polyoxidometalate. These H+ ions and the disordered solvent contribution were not included in the reported mol­ecular weight and density.

Cyclo­hexa­phospho­ric acid (P6O18H6) reacts with cadmium carbonate and 4-chloro­benzyl­amine (CBA) to give the mononuclear title complex, (C7H9ClN)4[Cd(P6O18)]n, in which the CdII atom, lying on an inversion centre, has an octa­hedral coordination built of six O atoms of two centrosymmetric P6O18 rings. Each P6O18 ligand acts as a bridge, linking two CdII atoms and forming an anionic coordination polymer [Cd(P6O18)4−]n extending along [010]. Adjacent polymeric chains are connected through N—H⋯O and C—H⋯O hydrogen bonds, generating a three-dimensional supra­molecular network.

20.  Diaqua­(2,2′-bipyridine-5,5′-dicarboxyl­ato-κ2 N,N′)(ethyl­enediamine-κ2 N,N′)copper(II) 2.5-hydrate 
In the mol­ecule of the title compound, [Cu(C12H6N2O4)(C2H8N2)(H2O)2]·2.5H2O, the CuII atom is six-coordinated in a distorted octa­hedral configuration by two N atoms from a 2,2′-bipyridine-5,5′-dicarboxyl­ate anion, two N atoms from ethyl­enediamine and two O atoms from two water mol­ecules. There are also two and a half water mol­ecules in the asymmetric unit. The planar five-membered ring is nearly coplanar with the adjacent pyridine rings, while the other five-membered ring adopts a twisted conformation, probably due to hydrogen bonding. In the crystal structure, intra- and inter­molecular N—H⋯O and O—H⋯O hydrogen bonds link the mol­ecules.

All of the CuII atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octa­hedral geometry with N2O4 and N4O2 environments for the outer and central CuII atoms, respectively. Various inter­actions, including numerous O—H⋯O and C—H⋯O hydrogen bonds and C—O⋯π stacking of the pyridine and carboxyl­ate groups [O⋯centroid distances = 3.669 (2) and 3.668 (2) Å] are observed in the crystal structure.

The complete dianionic ligand is generated by crystallographic twofold symmetry. In the crystal, a two-dimensional supra­molecular structure parallel to (001) is formed through O—H⋯O hydrogen-bond inter­actions between the coordinated water mol­ecules and the O atoms of nearby carboxyl­ate groups.

The title compound, {[Co3(C6H4NO2)2(C8H3NO6)2(H2O)2]·4H2O}n, exhibits a two-dimensional layer-like structure in which the CoII ions exhibit two kinds of coordination geometries. One nearly octa­hedral CoII ion with crystallographic inversion symmetry is coordinated to six carboxyl­ate O atoms from four bridging 5-nitro­isophthalate (NIPH) ligands and two isonicotinate (IN) anions, while the other type of CoII ion binds with one N atom and one carboxyl­ate O atom from two IN anions, two carboxyl­ate O atoms from two different NIPH anions and one ligated water mol­ecule, displaying a distorted square-pyramidal coordination geometry. Three adjacent CoII ions are bridged by six carboxyl­ate groups from four NIPH ligands and two IN anions to form a linear trinuclear secondary building unit (SBU). Every trinuclear SBU is linked to its nearest neighbours in the ab plane, resulting in a two-dimensional layer-like structure perpendicular to the c axis. Along the a-axis direction neighbouring mol­ecules are connected through carboxyl­ate and pyridyl units of the IN anions, along the b axis through carboxyl­ate groups of the NIPH ligands. The H atoms of one free water mol­ecule are disordered in the crystal in a 1:1 ratio. Typical O—H⋯O hydrogen bonds are observed in the lattice, which include the following contacts: (a) between coordinated water mol­ecules and carboxyl­ate O atoms of the NIPH anions, (b) between lattice water mol­ecules and carboxyl­ate O atoms of the NIPH anions, and (c) between coordinated and lattice water mol­ecules. These inter­molecular hydrogen bonds connect the two-dimensional layers to form a three-dimensional supra­molecular structure.
