Carbonyl-bis-(triphenyl-phosphane-?P)(?(2)-1-vinyl-pyrrolidin-2-one-?O)ruthenium(0).

ABSTRACT: The 1-vinyl-pyrrolidin-2-one ligand in the title compound, [Ru(C(6)H(9)NO)(C(18)H(15)P)(2)(CO)], coordinates to the Ru(0) atom with the olefin double bond and the ketone O atom. The Ru(0) atom adopts a distorted trigonal-bipyramidal coordination geometry, with the C O ligand and the ketone O atom occupying the axial positions. The two triphenyl-phosphane ligands are cis to each other. The olefinic C=C bond is almost coplanar with the Ru(0) atom and the two P atoms (maximum deviation of 0.0516?Å from the mean plane defined by the five constituent atoms). The coordinated C=C bond has a length of 1.449?(3)?Å, which is significantly longer than that of a free C=C bond (1.34?Å). There are two C-H?? inter-actions involving neighbouring phenyl rings in the mol-ecule. In the crystal, mol-ecules are linked via two further C-H?? inter-actions.

[1,1'-Bis(diphenyl-phosphan-yl)cobalto-cenium]carbonyl-chloridohydrido(triphenyl-phosphane)ruthenium(II) hexa-fluoridophosphate dichloro-methane disolvate.

Project description:In the title compound, [CoRu(C(17)H(14)P)(2)ClH(C(18)H(15)P)(CO)]PF(6)·2CH(2)Cl(2), the Ru(II) atom is coordinated by three P atoms from a chelating 1,1'-bis-(diphenyl-phosphan-yl)cobaltocenium ligand and a triphenyl-phosphine ligand, one CO ligand, one Cl atom and one H atom in a distorted octa-hedral geometry. In the cobaltocenium unit, the two cyclo-penta-dienyl rings are almost parallel, making a dihedral angle of 1.2?(3)°. The F atoms of the hexa-fluoridophosphate anion are disordered over two sets of sites, with an occupancy ratio of 0.849?(11):0.151?(11). Intra-molecular C-H?Cl hydrogen bonds occur in the complex cation. The complex cations, hexa-fluoridophosphate anions and dichloro-methane solvent mol-ecules are linked by inter-molecular C-H?F hydrogen bonds.

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.

Di-?-carbonyl-bis-[bis-(triphenyl-phos-phane)rhodium(0)](Rh-Rh) acetone disolvate.

Project description:The dirhodium complex, [Rh(2)(C(18)H(15)P)(4)(CO)(2)]·2(CH(3))(2)CO, has crystallographic twofold symmetry and the Rh-Rh distance is 2.6266?(8)?Å. The four atoms proximate to each Rh atom [Rh-P = 2.3222?(7) and 2.3283?(8)?Å, and Rh-C = 1.961?(3) and 2.045?(3)?Å] form a distorted tetra-hedron with large deviations from the putative tetra-hedral angles [r.m.s. deviation = 23?(1)°]. The six angles more closely approximate those of a trigonal bipyramid [r.m.s. deviation = 14?(1)°] with one missing equatorial ligand. The two bridging carbonyl ligands are much more linearly coordinated to one Rh [Rh-C O = 151.0?(2)°] than to the other [127.0?(2)°], and the two Rh(2)CO planes form a dihedral angle of 45.43?(5)°. The two acetone solvent mol-ecules are disordered, and their estimated scattering contribution was subtracted from the observed diffraction data using the SQUEEZE routine in PLATON [Spek (2009 ?).

trans-Tetra-carbonyl-bis-[tris-(3-fluoro-phen-yl)phosphane]chromium(0).

Project description:In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes, which are trans to each other. 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. Each of the F atoms is disordered over two positions with refined occupancies of 0.944?(3):0.056?(3), 0.702?(4):0.298?(4), 0.829?(4):0.171?(4), 0.567?(4):0.433?(4), 0.545?(4):0.455?(4) and 0.920?(4):0.080?(4).

Dicarbonyl-chlorido(phen-oxy-thio-carbonyl-?C,S)bis-(triphenyl-phosphane-?P)molybdenum(II).

Project description:In the title complex, [Mo(C(7)H(5)OS)Cl(C(18)H(15)P)(2)(CO)(2)], the geometry around the metal atom is a capped octa-hedron. The phen-oxy-thio-carbonyl ligand coordinates the Mo(II) atom through the C and S atoms. A one-dimensional structure is formed by ?-? inter-molecular inter-actions and a supra-molecular aggregation is determined by inter-molecular C-H?O, C-H?Cl, C-H??(arene) hydrogen bonds and CO??(arene) inter-actions [O?centroid distances = 3.485?(4) and 3.722?(3)?Å].

Dichlorido(3-phenyl-indenyl-idene)bis-(triphenyl-phosphane)ruthenium(II) tetra-hydro-furan disolvate.

Project description:The Ru(II) atom in the title compound, [RuCl(2)(C(15)H(10))(C(18)H(15)P)(2)]·2C(4)H(8)O, has a distorted square-pyramidal conformation. The P and Cl atoms are at the base of the pyramid and the Ru-C(indenyl-idene) bond is in the axial position. The two Cl ligands and the two phosphane ligands are in trans positions. The Cl-Ru-Cl and P-Ru-P angles are 157.71?(2) and 166.83?(2)°, respectively. The two independent tetra-hydro-furan (THF) solvent mol-ecules are disordered. One THF mol-ecule was refined using a split-atom model. The second THF mol-ecule was accounted for by using program PLATON/SQUEEZE [Spek (2009 ?). Acta Cryst. D65, 148-155]. The molecular conformation shows three intramolecular C-H?Cl contacts and two C-H?? interactions while the crystal packing features an intermolecular C-H?Cl contact and two very weak intermolecular C-H?? contacts.

The average Ru-P, Ru-N and Ru-Cl bond lengths are 2.325?(18), 2.1845?(7) and 2.4123?(12)?Å, respectively.

Carbonyl-chlorido(1-methyl-sulfanylpenta-1,3-dien-1-yl-5-yl-idene)bis-(triphenyl-phosphane)osmium(II).

Project description:The crystal structure of the title compound, [Os(C(6)H(7)S)Cl(C(18)H(15)P)(2)(CO)], confirms the formulation as an osmabenzene. There is a slightly distorted octa-hedral coordination environment at the Os(II) ion, with the triphenyl-phosphane ligands mutually trans and the chloride cis to the carbon bearing the -SMe substituent. Within the metallacyclic ring, the C-C distances are appropriate for aromatic bonds and the two Os-C distances are shorter than typical Os-C single bonds. The maximum deviation from the least-squares plane through the osmabenzene ring occurs for the carbon bearing the SMe substituent [0.1037?(18)?Å].

Bis(dimethyl sulfoxide)-hydridobis(triphenyl-phosphane)cobalt(I).

Project description:The title compound, [CoH(C(18)H(15)P)(2)(C(2)H(6)OS)(2)], was synthesized by the reaction of chloridotris(triphenyl-phosphane)cobalt(I), [ClCo(PPh(3))(3)], in the presence of one equivalent potassium hydridotris(pyrazol-yl)borate in dimethyl sulfoxide. The structure displays a distorted trigonal-pyramidally coordinated cobalt(I) atom, with two phosphane ligands and one DMSO ligand in the equatorial plane. The coordination is completed by one further DMSO ligand and the anionic hydride in the axial positions.
