Bis(?-diphenyl-arsine-?As:As)bis-[tetra-carbonyl-tungsten(0)].

ABSTRACT: The title compound, [W(2)(C(12)H(10)As)(2)(CO)(8)], features a diamond-shaped W(2)As(2) core with a W-W distance of 3.0948?(7)?Å. The coordination geometry for each W atom is based on a penta-gonal bipyramid within a As(2)C(4)W donor set, with carbonyl ligands defining the axial positions; the As atoms exist within distorted tetra-hedral C(2)W(2) donor sets.

Tetra-carbonyl-bis(?-cyclo-penta-dienyl)bis[(dec-9-en-1-yl)diphenyl-phosphine]dimolybdenum(0)(Mo-Mo) tetra-hydro-furan disolvate.

Project description:The asymmetric unit of the title compound, [Mo(2)(?(5)-C(5)H(5))(2)(C(22)H(29)P)(2)(CO)(4)]·2C(4)H(8)O, contains two half-mol-ecules of the organometallic species and two solvent mol-ecules. Both organometallic mol-ecules are completed by crystallographic inversion symmetry, yielding dimeric units with Mo-Mo single-bond lengths of 3.2703?(6) and 3.2548?(6)?Å. Each Mo atom is also coordinated by an ?(5)-cyclo-pentdienyl ligand, two carbonyl ligands, and a (dec-9-en-1-yl)diphenyl-phosphine ligand.

Bis{deca-carbonyl-bis-[μ-2,2'-(phenyl-imino)-diethano-lato]ditin(II)ditungsten(0)(2 Sn-W)} hexa-carbonyl-tungsten(0).

Project description:In the title 2:1 adduct, [Sn(2)W(2)(C(10)H(13)NO(2))(2)(CO)(10)](2)[W(CO)(6)], the complete hexa-carbonyl-tungsten mol-ecule is generated by a crystallographic inversion centre. The heterometallic mol-ecule features a central Sn(2)O(2) core with essentially equal Sn-O(eth-oxy) bond lengths. The second eth-oxy O and amine N atoms of each N,O,O'-tridentate ligand coordinate to one Sn atom only. The NO(3) donor atoms occupy basal positions and the W atom the apical position in a distorted square-pyramidal geometry for each Sn atom. The W atoms are approximately syn to each other but the central metal core is non-planar [W-Sn⋯Sn-W pseudo-torsion angle = 43.573 (16)°]. One of the carbonyl ligands in the heterometallic mol-ecule is disordered over two orientations with equal occupancies. In the crystal, the heterometallic mol-ecules associate via C-H⋯O inter-actions, forming supra-molecular layers with undulating topology in the ab plane. These stack along the c axis, defining voids which are occupied by the W(CO)(6) mol-ecules.

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.

Project description:The acetonitrile ligand in the title compound, [W(CH(3)CN)(CO)(5)], is coordinated end-on to a penta-carbonyl-tungsten(0) fragment with a W-N bond length of 2.186?(4)?Å, completing an octa-hedral coordination environment around the W atom.

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).

(Benzene-carbothio-amide-?S)-penta-carbonyl-tungsten(0).

Project description:The asymmetric unit of the title complex, [W(C(7)H(7)NS)(CO)(5)], comprises two independent mol-ecules. In each, the W atom is coordinated by five CO groups and the S atom of the benzencarbothioamide ligand in a distorted octa-hedral geometry. The crystal packing can be described as undulating layers of W(CO)(5) and benzene-carbothio-amide parallel to (001). In the crystal, components are linked via inter-molecular N-H?O and C-H?O hydrogen bonds to form a dimeric chains along the [010] direction. Intra-molecular N-H?C inter-actions are also observed.
