The RuII atom in the title compound, [RuCl2(C31H29N2P)(CO)2]·CH2Cl2, exhibits a distorted octahedral coordination environment. The bond angles of the cis substituents at the RuII atom range from 82.72 (9) to 97.20 (3)°. This mol­ecule is of inter­est in the field of catalytic transfer hydrogenation.

The title compound, [FeRu(C5H5)(C2N3)(C17H14P)2], was obtained by reaction of Cp(dppf)RuCl [dppf = 1,1′-bis­(diphenyl­phosphan­yl)ferrocene] with sodium dicyanamide in dichloro­methane. The RuII atom is capped by an η5-cyclo­penta­dienyl (Cp) ring, a chelating dppf and a terminal C2N3 unit, giving three-legged piano-stool geometry. The C—N—C angle of the N(CN)2 ligand [120.8 (6)°] is significantly smaller than that in the corresponding diruthenium complex [127.2 (9)°; Zhang et al. (2003 ▶). Inorg. Chem. 42, 633–640] due to steric hindrance between the two {Cp(PPh3)2Ru} building blocks. Disorder was found in the dichloro­methane solvent mol­ecule, which was refined as disordered over two positions, with a site-occupancy ratio of 0.53:0.47 (2).

The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C25H22P2)(C19H17PS)(CO)9]·CH2Cl2, contains one triangulo-triruthenium complex mol­ecule and one half-mol­ecule of the dichloro­methane solvent. The dichloro­methane solvent mol­ecule lies across a crystallographic inversion center leading to the mol­ecule being disordered over two positions of equal occupancy. The bis­(diphenyl­phosphan­yl)methane ligand bridges an Ru—Ru bond and the monodentate phosphane ligand bonds to the third Ru atom. All phosphane ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphane-substituted benzene rings make dihedral angles of 87.18 (11), 59.59 (10) and 89.28 (11)° with each other. The dihedral angles between the two benzene rings are 78.48 (11) and 87.58 (11)° for the two diphenyl­phosphanyl groups. In the crystal, the mol­ecules are stacked along the a axis. Weak inter­molecular C—H⋯π inter­actions stabilize the crystal structure.

In the dimeric title compound, [Pd2Cl4{P(C8H9)3}2]·CH2Cl2, the metal complex molecule is situated about an inversion centre and is accompanied by a dichloro­methane solvent mol­ecule situated on a twofold rotation axis. The PdII atom has a slightly distorted square-planar coordination sphere. The effective cone angle for the tris­(3,5-dimethyl­phen­yl)phos­phane ligand was calculated to be 169°. In the crystal, the metal complex and solvent mol­ecules are linked via C—H⋯Cl inter­actions, generating chains along [10-2]. There are also C—H⋯π and weak π–π inter­actions present [centroid–centroid distance = 3.990 (2) Å, plane–plane distance = 3.6352 (15) Å and ring slippage = 1.644 Å], forming of a three-dimensional structure.

In the title compound, [RuCl2(C6H14N2)(C28H28P2)]·CH2Cl2, the RuII ion is coordinated in a slightly distorted octa­hedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis­(diphenyl­phosphan­yl)butane ligand and two cis-chelating N atoms of a bidentate cyclo­hexane-1,2-diamine ligand. In the crystal, pairs of mol­ecules form inversion dimers via N—H⋯Cl hydrogen bonds. In addition, intra­molecular N—H⋯Cl and weak C—H⋯Cl, C—H⋯N, N—H⋯π and C—H⋯π hydrogen bonds are observed. One of the Cl atoms of the solvent mol­ecule is disordered over two sites with refined occupancies of 0.62 (1) and 0.38 (1).

In the title compound, [Ag{P(C6H11)2(C6H5)}2]ClO4·CH2Cl2, the AgI atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag—P = 2.3993 (4) and 2.4011 (4) Å; P—Ag—P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯Operchlorate inter­action of 2.873 (2) Å, which contributes to the slightly non-linear bond angle about the AgI atom. Weak inter­molecular C—H⋯O hydrogen-bonding inter­actions involving phenyl, cyclo­hexyl and dichloro­methane H-atom donors and perchlorate O-atom acceptors contribute to the stabilization of the crystal structure.

The PtII atom in the title compound, [Pt(C29H31NP2)2](PF6)2·2CH2Cl2, is coordinated by four P atoms from two bis­(di­phenyl­phosphan­yl)pentyl­amine ligands with an average Pt—P distance of 2.300 (1) Å. The coordination around the PtII atom shows a highly distorted square-planar geometry, as evidenced by the P—Pt—P bite angles of 70.45 (3) and 70.64 (3)°. The asymmetric unit contains two hexa­fluoridophosphate ions, the metal complex and two dichloro­methane solvent mol­ecules. One of the chloride atoms of one of the dichloro­methane mol­ecules is disordered over two sites in a 0.515 (3):0.485 (3) ratio. C—H⋯F hydrogen bonds stabilize the crystal packing.

The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclo­metalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloro­methane solvent mol­ecules create C—H⋯Cl inter­actions with the metal complex, generating supermolecular layers in the ab plane. Additional C—H⋯π and π–π [centroid–centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] inter­actions join these planes into a three-dimensional supermolecular network.

In the title compound, [Pd(CH3)Cl(C25H22NPS)]·0.5C2H2Cl2, the PdII atom is coordinated by the N,P-bidentate ligand, a methyl group and a chloride ion, generating a distorted square-planar PdCClNS coordination geometry, with the N and Cl atoms trans. The thio­phene ring is equally disordered over two orientations and the dichloro­methane solvent mol­ecule is disordered about an inversion centre.

The title complex, [RuCl2(C25H26N2)]·CH2Cl2, is best thought of as containing an octa­hedrally coordinated Ru center with the arene occupying three sites. Two Ru—Cl bonds and one Ru–carbene bond complete the distorted octa­hedron. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H2(CH3)3 arene group by a CH2 bridge. This leads to a system with very little apparent strain. A dichloro­methane solvent mol­ecule completes the crystal structure. Further stabilization is accomplished via C—H⋯N and C—H⋯Cl interactions.

In the title complex, [RhCl(C44H32OP2)]·CH3OH, the RhI ion is coordinated by a naphthyl group of a partially oxidized 2,2′-bis­(diphenyl­phosphan­yl)-1,1′-binaphthyl (BINAP) ligand in a η4 mode, one P atom of the diphenyl­phosphanyl group and one Cl atom. The P=O group does not inter­act with the RhI ion but accepts an O—H⋯O hydrogen bond from the methanol solvent mol­ecule.

The asymmetric unit of the title compound, [FeRuCl(C5H5)(C10H14)(C37H31P2)]PF6, contains two independent, geometrically similar RuII complexes of a chiral ferrocenyldiphosphane with piano-stool coordination through the η6-bound p-cymene ligand, two chelating phospho­rus donor atoms, and an exo-oriented chloride ion. The mean bond lengths of the two Ru complexes are Ru—C = 2.276 Å, Ru—P = 2.3816 Å, and Ru—Cl = 2.3924 Å. Both chloride ligands form only intra­molecular C—H⋯Cl inter­actions. Seven weak inter­molecular C—H⋯F inter­actions involving mainly arene H atoms consolidate the crystal packing, which reveals an approximate c/2 pseudo-translation relating the two independent Ru complex mol­ecules.

In the title solvated complex, [NiCl2(C31H27NP2)]·CH2Cl2, the Ni2+ ion is coordinated by two chloride ions and two P atoms of the chelating N,N-bis­(diphenyl­phosphan­yl)benzyl ligand to generate a strongly distorted cis-NiCl2P2 square-planar geometry for the metal ion. In the crystal, the components are linked by C—H⋯Cl inter­actions.

In the title compound, [CoRu(C17H14P)2ClH(C18H15P)(CO)]PF6·2CH2Cl2, the RuII atom is coordinated by three P atoms from a chelating 1,1′-bis­(diphenyl­phosphan­yl)cobaltocenium ligand and a triphenyl­phosphine ligand, one CO ligand, one Cl atom and one H atom in a distorted octa­hedral geometry. In the cobaltocenium unit, the two cyclo­penta­dienyl rings are almost parallel, making a dihedral angle of 1.2 (3)°. The F atoms of the hexa­fluoridophosphate anion are disordered over two sets of sites, with an occupancy ratio of 0.849 (11):0.151 (11). Intra­molecular C—H⋯Cl hydrogen bonds occur in the complex cation. The complex cations, hexa­fluoridophosphate anions and dichloro­methane solvent mol­ecules are linked by inter­molecular C—H⋯F hydrogen bonds.

The title compound, [Pd(C26H45S4)Cl]·CH2Cl2, crystallizes with a disordered dichloro­methane solvent mol­ecule [occupancy ratio = 0.67 (4):0.33 (4)]. Two of the tert-butyl groups are also disordered [occupancy ratios = 0.70 (5):0.30 (5) and 0.63 (4):0.37 (4)]. Although the pincer ligand offers the possibility for coordination of two different metal atoms, the present structure shows only the coordination of a single PdII atom in a typical S—C—S tridentate pincer manner. The PdII atom is in a slightly distorted square-planar environment with the two tert-butyl­sulfanyl groups arranged in a trans con­formation and with a chloride ligand trans to the σ-bonded aromatic C atom. The structure exhibits a durene-like ligand frame, forming a dihedral angle of 13.6 (4)° with the metal coordination (Pd/S/S/Cl/C) environment. It is noteworthy that the tert-butyl groups are found in a syn arrangement, this being different to that found previously by Loeb, Shimizu & Wisner [(1998). Organometallics, 17, 2324–2327].

The square-planar Pt2+ coordination sphere is slightly distorted with the bidentate ligand coordinated via the P and the amine N atoms, and the Cl atoms located cis at the two remaining coordination sites. Parts of the thiophene ring and the solvate molecule were modeled as disordered with occupancy ratios of 0.55 (2):0.45 (2) and 0.302 (10):0.198 (10), respectively. Weak C—H⋯Cl inter­actions stabilize the crystal packing.

The asymmetric unit of the title complex, [Sb(C44H28N4)Cl2][Sb2Cl8]0.5·CH2Cl2, is composed of a SbV complex cation wherein the Sb atom is hexa­coordinated by four N atoms of the pyrrole rings of the tetra­phenyl­porphyrinate (TPP) ligands and two chloride ions, a half di-μ-chlorido-bis­[trichloridoanti­monate(III)] counter-anion and a dichloro­methane solvent mol­ecule. In the cation, the average Sb—N distance is 2.066 (2) Å, while the Sb—Cl distances are 2.3410 (11) and 2.3639 (12) Å. The central unit of the cation, SbN4C20, is far from being planar, with deviations of atoms from the least-squares plane ranging from −0.110 (4) to 0.124 (4) Å. The Sb—Cl distances in the anion, which is located about an inversion center, lie in the wide range 2.3715 (13)–2.7489 (13) Å, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by inter­molecular C—H⋯Cl inter­actions involving the cations, the anions and the solvent mol­ecules.

The PdC3P and PdC2P2 five-membered metallacycles adopt envelope and twist conformations, respectively. In the crystal, inter­molecular C—H⋯O hydrogen bonds link cations and anions into a three-dimensional network. The dichloro­methane solvent mol­ecule is disordered over three orientations with a site-occupancy ratio of 0.5/0.3/0.2. The n-hexane solvent mol­ecule has a crystallographically imposed centre of symmetry.

In the title compound, [Pd(C7H7O2S)Cl(C44H32P2)]·3CH2Cl2·H2O, the geometry around the metal atom is distorted square planar, with a twist angle between the P—Pd—P and S—Pd—Cl planes of 28.11 (2)°. The two Pd—P bond lengths differ by about 0.04 Å and the biphosphane bite angle is slightly obtuse [92.92 (2)°]. There are three dichloro­methane and one water mol­ecule co-crystallized with the palladium mol­ecule, all with atoms in general positions. Alternating water and palladium mol­ecules form four-membered cyclic units through O—H⋯Cl and O—H⋯O hydrogen bonding. One of the dichloromethane solvent molecules is disordered over two positions in a 0.55:0.45 ratio.

The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the PdII atom situated on an inversion centre) and a dichloro­methane molecule in the asymmetric unit. The independent PdII atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl—Pd—P angles ranging from 86.151 (19) to 93.849 (19)° are evident. The effective cone angles for the tris­[4-(trifluoro­meth­yl)phen­yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C—H⋯Cl/F inter­actions create a three-dimensional supramolecular network. Loose packing at two of the –CF3 groups resulted in large thermal vibrations which were treated as two-component disorders [occupancy ratios 0.50:0.50 and 0.628 (15):0.372 (15)].

The two symmetry-equivalent nitrate anions are weakly coordinated to the PtII ion, creating, together with four P ligand atoms, a distorted octa­hedral coordination environment. In addition, several close C—H⋯O contacts between the nitrate O atoms and phenyl H atoms are found. Hydrogen bonds from two methanol solvent mol­ecules to one of the O—P groups complete the crystal structure.

In the crystal structure of the title compound, [Cu(C18H16N6)(C36H28OP2)]PF6·0.5CH2Cl2 or [Cu(DPEPhos)(Bn-bta)]PF6·0.5CH2Cl2 {DPEPhos = bis­[(diphenyl­phosphan­yl)phen­yl] ether and Bn-bta = 1,1′-dibenzyl-1H,1′H-4,4′-bi-1,2,3triazol­e}, the Cu atom is coordinated by two N and two P atoms of the ligands in a strongly distorted tetra­hedral environment.
