Penta-carbonyl-2?C-chlorido-1?Cl-bis-[1(?)-cyclo-penta-dien-yl](?-1-oxido-ethyl-ene-1:2?O:C)chromium(0)zirconium(IV).

ABSTRACT: The title compound, [CrZr(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)], consists of two metal centres, with a (penta-carbonyl-chromium)oxymethyl-carbene group coordinating as a monodentate ligand to the zirconocene chloride. ?-Delocalization through the Zr-O-C=Cr unit is indicated by a short Zr-O distance [2.041?(3)?Å] and a nearly linear Zr-O-C angle [170.5?(3)°]. Mol-ecules are aligned with their mol-ecular planes (through Zr, Cl, carbene and Cr) parallel to the ab plane. C-H?Cl inter-actions result in zigzag chains of mol-ecules propagating parallel to the b axis.

Project description:In the mol-ecular structure of the dinuclear title compound [?(5)-(C5(CH3)5)(CO)Fe{(?-BCl)(?-CO)}PtCl(P(C6H11)3)]·C6H6, the two metal atoms, iron(II) and platinum(II), are bridged by one carbonyl (?-CO) and one chlorido-borylene ligand (?-BCl). The Pt(II) atom is additionally bound to a chloride ligand situated trans to the bridging borylene, and a tri-cyclo-hexyl-phosphane ligand (PCy3) trans to the carbonyl ligand, forming a distorted square-planar structural motif at the Pt(II) atom. The Fe(II) atom is bound to a penta-methyl-cyclo-penta-dienyl ligand [?(5)-C5(CH3)5] and one carbonyl ligand (CO), forming a piano-stool structure. Additionally, one benzene solvent mol-ecule is incorporated into the crystal structure, positioned staggered relative to the penta-methyl-cyclo-penta-dienyl ligand at the Fe(II) atom, with a centroid-centroid separation of 3.630?(2)?Å.

Dibromido[bis-(η-cyclo-penta-dien-yl)dimethyl-silane]zirconium(IV).

Project description:The title mol-ecule, [ZrBr(2)(C(12)H(14)Si)], possesses a crystallographically imposed twofold rotational symmetry with the rotation axis passing through the Zr and Si atoms. The Zr(IV) centre is in a distorted tetra-hedral environment defined by two Cp rings of chelating organic ligands and two Br anions. Two five-membered rings form a dihedral angle of 59.7 (2)°. Unequal Zr-C bonds [2.471 (3)-2.556 (3) Å] in the mol-ecule indicate that the inter-action of the central metal with the [(C(5)H(4))(2)SiMe(2)](2-) ligand contains noticeable η(3)-allyl and η(2)-olefin contributions.
