1.  catena-Poly[(di­aqua­cadmium)-μ-iminodi­acetato-κ4 O,N,O′:O′′] 
In the title compound, [Cd(C4H5NO4)(H2O)2]n, the CdII atom exhibits a distorted octa­hedral coordination geometry, defined by one N atom and three O atoms from two iminodi­acetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another CdII atom, thus forming a zigzag chain along [001]. A three-dimensional network is completed by inter­molecular O—H⋯O and N—H⋯O hydrogen bonds.

2.  μ-Oxalato-κ4 O 1,O 2:O 1′,O 2′-bis­[aqua­(2,2′-bipyridine-κN)(nitrato-κ2 O,O′)lead(II)] 
The title compound, [Pb2(C2O4)(NO3)2(C10H8N2)2(H2O)2], was synthesized hydro­thermally. The binuclear complex mol­ecule is centrosymmetric, the inversion centre being located at the mid-point of the oxalate C—C bond. The PbII ion is hepta­coordinated by the O atom of one water mol­ecule, two oxalate O atoms, two nitrate O atoms and two 2,2′-bipyridine N atoms, forming an irregular coordination environemnt. Inter­molecular O—H⋯O hydrogen bonds between water mol­ecules and oxalate and nitrate ions result in the formation of layers parallel to (010). π–π inter­actions between pyridine rings in adjacent layers, with centroid–centroid distances of 3.584 (2) Å, stabilize the structural set-up.

3.  Poly[[μ2-aqua-μ3-(4-carb­oxy-2-propyl-1H-imidazole-5-carboxyl­ato-κ4 N 3,O 4:O 4:O 5)-sodium] hemihydrate] 
In the title compound, {[Na(C8H9N2O4)(H2O)]·0.5H2O}n, the Na+ ion is coordinated by two bridging water mol­ecules, one N atom and three O atoms from three 4-carb­oxy-2-propyl-1H-imidazole-5-carboxyl­ate (H2pimdc) ligands. Adjacent Na+ ions are linked alternately by two water O atoms and two carb­oxy O atoms into a chain along [001]. These chains are connected through the coordination of the carboxyl­ate O atoms to the Na+ ions, forming a three-dimensional structure. An intra­molecular O—H⋯O hydrogen bond and inter­molecular N—H⋯O and O—H⋯O hydrogen bonds are present in the crystal structure.

4.  Diaqua­bis­[2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl-κN 3)nicotinato-κN]manganese(II) 
In the title compound, [Mn(C13H14N3O3)2(H2O)2], the MnII ion is coordinated by four N atoms from two (±)-2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinate ligands and two water mol­ecules in a distorted octa­hedral environment. Inter­molecular O—H⋯O hydrogen bonds lead to a chain along [010]. Intra­molecular N—H⋯O and O—H⋯O hydrogen bonds are observed.

5.  Diaqua­bis­[2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinato]cobalt(II) 
In the title complex, [Co(C13H14N3O3)2(H2O)2], the CoII atom has a distorted octa­hedral coordination, formed by four N atoms from two (±)-2-(5-isopropyl-5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl)nicotinate ligands and two O atoms from two water mol­ecules. Intra­molecular N—H⋯O and O—H⋯O hydrogen bonds are present. In the crystal, inter­molecular O—H⋯O hydrogen bonds link the complex mol­ecules into a chain along [010].

6.  3-Chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinic acid–triphenyl­phosphine oxide (1/1) 
In the title 1:1 adduct, C11H10ClN3O2·C18H15OP, the dihedral angle between the pyridine and pyrazole rings is 10.3 (2)°. The two components of the adduct are linked by an O—H⋯O hydrogen bond.

7.  Poly[[μ-chlorido-μ-[2-(2,4-di­fluoro­phen­yl)-1,3-bis­(1,2,4-triazol-1-yl)propan-2-ol-κ2 N 4:N 4′]-zinc] chloride dihydrate] 
The title compound, {[ZnCl(C13H12F2N6O)2]Cl·2H2O}n, is a two-dimensional coordination polymer. The ZnII atom is six-coordinated by four N atoms from four 2-(2,4-di­fluoro­phen­yl)-1,3-bis­(1,2,4-triazol-1-yl)propan-2-ol (HFlu) ligands and by two Cl atoms in a distorted octa­hedral geometry. Two Cl atoms bridge two ZnII atoms, forming a centrosymmetric dinuclear unit. The HFlu ligands connect the dinuclear units into a 44 net parallel to (001) when the dinuclear unit is considered as a node. O—H⋯O and O—H⋯Cl hydrogen bonds link the cationic layer, free chloride anions and lattice water mol­ecules. Intra­layer π–π inter­actions between the triazole rings are observed [centroid–centroid distance = 3.716 (6) Å].

8.  Aqua­[2-(5-ethyl-2-pyridyl-κN)-4-iso­propyl-4-methyl-5-oxo-4,5-dihydroxy­imidazol-1-ido-κN 1](5-methyl-1H-pyrazole-3-carboxyl­ato-κ2 N 2,O)copper(II) 1.33-hydrate 
In the title complex, [Cu(C5H5N2O2)(C14H18N3O)(H2O)]·1.33H2O, the CuII ion is coordinated in a slightly distorted square-pyramidal environment. The basal plane is formed by two N atoms from a 2-(5-ethyl-2-pyridyl-κN)-4-isopropyl-4-methyl-5-oxo-4,5-dihydroxy­imidazol-1-ide ligand and by one O atom and one N atom from a 5-methyl-1H-pyrazole-3-carboxyl­ate ligand. The apical position is occupied by a water mol­ecule. In the crystal structure, O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds lead to a three-dimensional supra­molecular network.

9.  Bis[μ-2-(2,4-difluoro­phen­yl)-1,3-bis­(1,2,4-triazol-1-yl)propan-2-olato-κ4 N 2,O:O,N 2′]bis­[(acetato-κ2 O,O′)nickel(II)] methanol hemisolvate 
In the title complex, [Ni2(C13H11F2N6O)2(C2H3O2)2]·0.5CH3OH, there are two half-molecules in the asymmetric unit. The two centrosymmetrically related NiII atoms, each attached to an acetate ligand, are linked by two fluconazole ligands. Each NiII atom is six-coordinated in a distorted octa­hedral geometry by two N atoms of the triazole groups and two bridging O atoms from two different fluconazole ligands and two O atoms from a chelating acetate ligand. In the crystal structure, the half-occupied methanol solvent mol­ecule is linked to a triazole group via an O—H⋯N hydrogen bond.
