Trans-Tetra-carbonyl-bis-(tri-phenyl-phosphane-?P)molybdenum(0).

ABSTRACT: 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.

The three benzene rings in one phosphane ligand make dihedral angles of 53.50?(9), 75.51?(10) and 80.63?(10)° with each other, while in the other ligand these angles are 51.92?(10), 78.56?(11) and 86.80?(10)°. C-H?O and C-H?F inter-actions link the mol-ecules into a three-dimensional network.

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 bis-[tetra-kis-(tri-phenyl-phosphane-κP)silver(I)] (nitrilo-tri-acetato-κ(4) N,O,O',O'')(tri-phenyl-phosphane-κP)argentate(I) with an unknown amount of methanol as solvate.

Project description:The structure of the title compound, [Ag(C18H15P)4]2[Ag(C6H6NO6)(C18H15P)], exhibits trigonal (P-3) symmetry, with a C 3 axis through all three complex ions, resulting in an asymmetric unit that contains one third of the atoms present in the formula unit. The formula unit thus contains two of the cations, one anion and disordered mol-ecules of methanol as the packing solvent. Attempts to refine the solvent model were unsuccessful, indicating uninter-pretable disorder. Thus, the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18] was applied, accounting for 670 electrons per unit cell, representing approximately 18 mol-ecules of methanol in the formula unit. The stated crystal data for M r, μ etc do not take these into account.

trans-Bis(μ-benzene-thiol-ato-κ(2) S:S)bis[chlorido-(tri-phenyl-phosphane-κP)palladium(II)] chloro-form disolvate.

Project description:The title compound, [Pd2Cl2(C6H5S)2(C18H15P)2]·2CHCl3, contains a centrosymmetric dinuclear palladium complex with the Pd(II) cation in a slightly distorted square-planar coordination environment. The Pd(II) cations are bridged by the S atoms of two benzene-thiol-ate ligands with different Pd-S distances [2.2970 (11) and 2.3676 (11) Å]. The coordination of the metal atom is completed by a chloride anion [2.3383 (11) Å] and a tri-phenyl-phosphane ligand [2.2787 (11) Å]. Weak C-H⋯Cl inter-actions are present between complex mol-ecules and the CHCl3 solvent mol-ecule. The latter is disordered over two positions in a 0.792 (8):0.208 (8) ratio. The crystal under investigation was found to be twinned by nonmerohedry, with a fraction of 73.4 (1)% for the major twin component.

Crystal structure of bromido-nitro-syl-bis(tri-phenyl-phosphane-κP)nickel(II).

Project description:The asymmetric unit of the title complex, [NiBr(NO){P(C6H5)3}2], comprises two independent mol-ecules each with a similar configuration. The Ni(II) cation is coordinated by one bromide anion, one nitrosyl anion and two tri-phenyl-phosphane mol-ecules in a distorted BrNP2 tetra-hedral coordination geometry. The coordination of the nitrosyl group is non-linear, the Ni-N-O angles being 150.2 (5) and 151.2 (5)° in the two independent mol-ecules. In the crystal, mol-ecules are linked by weak C-H⋯Br hydrogen bonds and weak C-H⋯π inter-actions into a three-dimensional supra-molecular architecture.

<i>trans</i>-Carbonyl-chlorido-bis-(tri-ethyl-phosphane-κ<i>P</i>)platinum(II) tetra-fluorido-borate.

Project description:The chemical formulation of the title compound was established as trans-[PtCl{P(C2H5)3(CO)}BF4 by single-crystal X-ray analysis, in contrast to the five-coordinate tetra-fluoro-ethyl-ene complex that had been anti-cipated. The compound had been prepared by reaction of trans-PtHCl(P(C2H5)3)2 with C2F4 in the absence of air, and the presence of the carbonyl group was not suspected. The square-planar cations and BF4 - anions are linked by C-H⋯F and C-H⋯O inter-actions into thick wavy (010) sheets. The present crystal-structure refinement is based on the original intensity data recorded in 1967.

(anti-Chlorido-thio-semicabazide-κS)bis-(tri-phenyl-phosphane-κP)copper(I) 0.48-hydrate.

Project description: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).

μ-Oxido-bis-[hydridotris(tri-methyl-phosphane-κP)iridium(III)](Ir-Ir) bis-(tetra-fluorido-borate) dihydrate.

Project description:The title compound, [Ir2H2O(C3H9P)6](BF4)2·2H2O, was isolated from the reaction between [Ir(COD)(PMe3)3]BF4 and H2 in water (COD is cyclo-octa-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe3 groups, one hydride ligand and half an oxide ligand, in addition to a BF4 (-) counter-ion and one water molecule of hydration. The single oxide ligand bridging two Ir(III) atoms is disordered across an inversion center with each O atom having a 50% site occupancy. Each Ir(III) atom has three PMe3 groups occupying facial positions, with the half-occupancy O atoms, a hydride ligand and an Ir-Ir bond completing the coordination sphere. The Ir-Ir distance is 2.8614 (12) Å, comparable to other iridium(III) metal-metal bonds. Two water mol-ecules hydrogen bond to two BF4 (-) anions in the unit cell.
