Crystal structures of trans-acetyl-dicarbon-yl(?(5)-cyclo-penta-dien-yl)(di-methyl-phenyl-phosphane)molybdenum(II) and trans-acetyl-dicarbon-yl(?(5)-cyclo-penta-dien-yl)(ethyl-diphenyl-phosphane)molybdenum(II).

Project description:The title compounds, [Mo(C5H5)(COCH3)P(CH3)2(C6H5)(CO)2], (1), and [Mo(C5H5)(COCH3)P(C2H5)(C6H5)2)(CO)2], (2), have been prepared by phosphine-induced migratory insertion from [Mo(C5H5)(CO)3(CH3)]. Both complex mol-ecules exhibit a four-legged piano-stool geometry with trans-disposed carbonyl ligands along with Mo-P bond lengths and C-Mo-P angles that reflect the relative steric pressure of the respective phosphine ligand. The structure of compound (1) exhibits a layered arrangement parallel to (100). Within the layers mol-ecules are linked into chains along [001] by non-classical C-H?O inter-actions between the acetyl ligand of one mol-ecule and the phenyl and methyl phosphine substituents of another. In the structure of complex (2), a chain motif of centrosymmetrical dimers is found along [010] through C-H?O inter-actions.

Bromido-1?Br-tricarbonyl-2?C-(2?-cyclo-penta-dien-yl)molybdenum(I)tungsten(I)(W-Mo).

Project description:The title compound, [WMoBr(C(5)H(5))(CO)(3)], is built up from a pseudo-square-pyramidal piano-stool coordination around the Mo atom, the important geometry being Mo-W = 2.6872?(7)?Å, W-Br = 2.5591?(9)?Å and Mo-W-Br = 158.35?(3)°.

Dicarbon-yl(η-cyclo-penta-dien-yl)bis-(trimethyl-phosphine)molybdenum(II) trifluoro-methane-sulfonate.

Project description:In the title compound, [Mo(C(5)H(5))(CO)(2)(C(3)H(9)P)(2)]CF(3)SO(3), the cationic complex displays a classical four-legged piano-stool square-pyramidal geometry with a trans configuration of the basal ligands around the Mo atom. The cyclo-penta-dienyl (Cp) ligand occupies the apical position of the piano-stool configuration. The average Mo-P bond length of the two trans PMe(3) ligands is 2.474 (5) Å and the Mo-Cp centroid distance is 2.003 (2) Å.

trans-Acetyl-dicarbon-yl(η(5)-cyclo-penta-dien-yl)(methyl-diphenyl-phosphane)molybdenum(II).

Project description:The title compound, [Mo(C(5)H(5))(C(2)H(3)O)(C(13)H(13)P)(CO)(2)], was prepared by reaction of [Mo(CH(3))(C(5)H(5))(CO)(3)] with methyl-diphenyl-phosphane. The Mo(II) atom exhibits a four-legged piano-stool coordination geometry with the acetyl and phosphane ligands trans to each other. There are several inter-molecular C-H⋯O hydrogen-bonding inter-actions involving carbonyl and acetyl O atoms as acceptors. A close nearly parallel π-π inter-action between the cyclo-penta-dienyl plane and the phenyl ring of the phosphane ligand is present, with an angle of 6.4 (1)° between the two least-squares planes. The centroid-to-centroid distance between these groups is 3.772 (3) Å, and the closest distance between two atoms of these groups is 3.449 (4) Å. Since each Mo complex is engaged in two of these inter-actions, the complexes form an infinite π-stack coincident with the a axis.

[1,2-Bis(diphenyl-phosphino)ethane]-chlorido(?-penta-methyl-cyclo-penta-dien-yl)iron(II) dichloro-methane solvate.

Project description:In the title compound, [Fe(C(10)H(15))Cl(C(26)H(24)P(2))]·CH(2)Cl(2), the Fe(II) atom is coordinated by two P atoms from a 1,2-bis-(diphenyl-phosphino)ethane ligand [Fe-P = 2.2130?(7) and 2.2231?(7)?Å], a chloride anion [Fe-Cl = 2.3329?(7)?Å] and a penta-methyl-cyclo-penta-dienyl (Cp*) ligand [Fe-centroid(Cp*) = 1.732?(3)?Å] in a typical piano-stool geometry. In the crystal structure, the complex and solvent mol-ecules are paired via weak C-H?Cl inter-actions.

Chlorido(chloro-diphenyl-phosphine-κP)(diphenyl-piperidinophosphine-κP)(η-penta-methyl-cyclo-penta-dien-yl)ruthenium(II).

Project description:The title compound, [Ru(C(10)H(15))Cl(C(12)H(10)ClP)(C(17)H(20)NP)], is a half-sandwich complex of Ru(II) with the chloro-diphenyl-phosphine ligand formed from the diphenyl-piperidinophosphine and chlorine of the precursor complex [Ru(η(5)-C(5)Me(5))(κ(1)P-Ph(2)PNC(5)H(10))Cl(2)] by an unexpected reaction with NaBH(4). The complex has a three-legged piano-stool geometry, with Ru-P bond lengths of 2.2598 (5) Å for the chloro-phosphine and 2.3303 (5) Å for the amino-phosphine.

Bis(η-penta-methyl-cyclo-penta-dien-yl)cobalt(II).

Project description:The crystal structure of the title compound, deca-methyl-cobaltocene, [Co(C(10)H(15))(2)], has been determined. High-quality single crystals were grown from a cold saturated hexa-methyl-disiloxane solution. The structure is related to the manganese and iron analogs. The molecule has D(5d) symmetry, with the Co atom in a crystallographic 2/m position. The cobalt-centroid(C(5)) distance is 1.71Å and the centroid(C(5))-Co-centroid(C(5)) angle is 180°, by symmetry.

Bis[bis-(penta-methyl-cyclo-penta-dien-yl)cobalt(III)] tetra-chlorido-cobaltate(II) di-chloro-methane disolvate.

Project description:The title compound, [Co(C10H15)2]2[CoCl4]·2CH2Cl2, was isolated as a dichloromethane solvate and was formed in the reaction between lithium penta-methyl-cyclo-penta-dienide and anyhydrous cobalt(II) chloride in tetra-hydro-furan. There are two deca-methyl-cobaltocenium cations, one tetrachloridocobaltate(II) anion and two di-chloro-methane solvent mol-ecules in the formula unit. There is a slight disorder of the di-chloro-methane solvent which was treated with a two-site model [occupancy rates = 0.765?(4) and 0.235?(4)]. The di-chloro-methane mol-ecules display significant C-H?Cl inter-actions with the tetrachloridocobaltate(II) dianion. The cobalt atom of the deca-methyl-cobaltocenium cation sits on a twofold rotation axis, with only one penta-methyl-cyclo-penta-diene ligand being unique and the second generated by symmetry. The cobalt atom of the [CoCl4](-2) ion sits on a special site with -4 symmetry, with one unique chloride ligand and the others generated by the fourfold inversion axis.

trans-Acetyl-dicarbon-yl(η(5)-cyclo-penta-dien-yl)[tris-(furan-2-yl)phosphane-κP]molybdenum(II).

Project description:The title compound, [Mo(C5H5)(C2H3O)(C12H9O3P)(CO)2], was prepared by reaction of [Mo(C5H5)(CO)3(CH3)] with tris-(furan-2-yl)phosphane. The Mo(II) atom exhibits a four-legged piano-stool coordination geometry with the acetyl and phosphine ligands trans to each other. The O atom of the acetyl ligand points down, away from the Cp ring. In the crystal, mol-ecules form centrosymmetrical dimers via π-π inter-actions between furyl rings [the centroid-centroid distance is 3.396 (4) Å]. The dimers are linked by C-H⋯O hydrogen bonds into layers parallel to (100).
