(anti-Chlorido-thio-semicabazide-?S)bis-(tri-phenyl-phosphane-?P)copper(I) 0.48-hydrate.

ABSTRACT: In the mononuclear title complex, [CuCl(CH5N3S)(C18H15P)2]·0.48H2O, the Cu(I) ion is in a slightly distorted tetra-hedral coordination geometry formed by two P atoms from two tri-phenyl-phosphane ligands, one S atom from a thio-semicarbazide ligand and one chloride anion. An intra-molecular N-H?N hydrogen bond [graph-set motif S(5)] stabilizes the thio-semicarbazide ligand in its anti conformation, and an intra-molecular N-H?Cl hydrogen bond between the hydrazine N-H group and the chloride anion influences the arrangement and orientation of the ligands around the metal center. A weak intra-molecular C-H?Cl hydrogen bond is also present. In the crystal, complex mol-ecules are connected through N-H?Cl hydrogen bonds originating from the amide -NH2 group, and through O-H?S and O-H?Cl hydrogen bonds involving the solvent water mol-ecule. Both the direct N-H?Cl hydrogen bonds as well as the bridging hydrogen bonds mediated by the water mol-ecule connect the complex mol-ecules into zigzag chains that propagate along [010]. The solvent water mol-ecule is partially occupied, with a refined occupancy of 0.479?(7).

trans-Chlorido-(4-fluoro-benzene-thiol-ato-κS)bis-(tri-phenyl-phosphane-κP)palladium(II) methanol hemisolvate.

Project description:The title compound, [Pd(SC6H4F-p)Cl(PPh3)2]·0.5CH3OH, features a Pd(II) complex with two tri-phenyl-phosphane (PPh3) ligands arranged in a trans conformation, with one chloride and one 4-fluoro-benzene-thiol-ate ligand completing the coordination sphere, giving rise to a slightly distorted square-planar geometry of the Pd(II) ion. The methanol solvent mol-ecule is disordered about an inversion centre with an occupancy of 0.25 for each molecule. In the crystal, weak C-H⋯Cl hydrogen-bonding inter-actions between the complex mol-ecules generate chain frameworks parallel to [010].

Crystal structure of (1,3-di-methyl-thio-urea-κS)tris-(tri-phenyl-phosphane-κP)silver(I) acetate.

Project description:In the mononuclear title salt, [Ag(C3H8N2S)(C18H15P)3](CH3COO), the Ag(I) ion exhibits a distorted tetra-hedral coordination sphere defined by three P atoms from three tri-phenyl-phosphane ligands and one S atom from a 1,3-di--methyl-thio-urea ligand. In the crystal, the acetate anion is linked with the complex cation via duplex N-H⋯O hydrogen bonds [graph-set motif R (2) 2(8)].

Chlorido[5-meth-oxy-1H-benzimidazole-2(3H)-thione-κS]bis-(tri-phenyl-phos-phane-κP)copper(I) methanol disolvate.

Project description:In the title complex, [CuCl(C8H8N2OS)(C18H15P)2]·2CH3OH, the Cu(I) ion is coordinated by one chloride anion, one S atom from the 5-meth-oxy-1H-benzimidazole-2(3H)-thione ligand and two P atoms from two tri-phenyl-phosphine ligands in a distorted tetra-hedral geometry. One of the N-bound H atoms is involved in an intra-molecular N-H⋯Cl hydrogen bond, while another one inter-acts with the solvent methanol mol-ecule via an N-H⋯O hydrogen bond. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds link two further complex mol-ecules and four solvent mol-ecules into a centrosymmetric structural unit. The short distance of 3.624 (4) Å between the centroids of the five- and the six-membered rings of two benzimidazole fragments indicates the presence of π-π inter-actions.

Project description:In the title compound, [Ag2(C3H6N2S)4(C18H15P)2](C2H3O2)2·[Ag(C2H3O2)(C3H6N2S)(C18H15P)2]2·2C2H3N·4H2O, the Ag(I) ion in the mononuclear neutral complex exhibits a distorted tetra-hedral environment with coordination by two P atoms from tri-phenyl-phosphane (PPh3) ligands, one S atom of an imidazolidine-2-thione (etu) ligand and one O atom of an acetate anion. The binuclear cationic complex comprises two inversion-related [Ag(C3H6N2S)2(C18H15P)] units with Ag(I) ions bridged by two S atoms from etu ligands forming a four-membered Ag-S-Ag-S ring. Each Ag(I) ion is coordinated by a P atom of a PPh3 ligand, two S atoms of bridging etu ligands and the terminal S atom of an etu ligand in a distorted tetra-hedral environment. In the crystal, the mononuclear complex is linked to lattice water mol-ecules through O-H⋯O and N-H⋯O hydrogen bonds, forming a chain along [100]. In addition, the binuclear complex mol-ecules are connected to acetate anions and lattice water mol-ecules via O-H⋯O, N-H⋯O and O-H⋯S hydrogen bonds, also along [100].

The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis.

(Ferrocenyl-thio-phospho-nato-κS)(triphenyl-phosphane-κP)gold(I) dichloro-methane monosolvate.

Project description:In the title compound, [AuFe(C(5)H(5))(C(5)H(5)O(2)PS)(C(18)H(15)P)]·CH(2)Cl(2), the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P-Au-S bond angle of 176.81 (6)°. The difference in P=O and P-O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P-O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link dinuclear mol-ecules into chains propagated in the [010] direction. The dichloro-methane solvent mol-ecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.

trans-Tetra-carbonyl-bis-(tri-phenyl-phosphane-κP)molybdenum(0).

Project description:The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.
