چکیده
The title compound, [ZrW(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)] or [W(CO)(5)C(CH(3))OZr(C(5)H(5))(2)Cl], consists of two metal centres, with a (tungsten penta-carbon-yl)oxymethyl-carbene group coordinating as a monodentate ligand to the chloridozirconocene. The two halves of the mol-ecule are related by a crystallographic mirror plane. Delocalization through the Zr-O-C=W unit is indicated by a short Zr-O distance and a nearly linear Zr-O-C angle.

The title compound, [Zr₃(C₅H₅)₆Cl₂O₂], exists as discrete mol-ecules possessing a series of three Cp(2)Zr units (Cp is cyclo-penta-dien-yl) bridged by oxide ligands and end-capped by chloride ligands. The Cp planes in the central and terminal zirconocene units form dihedral angles of 53.3 (2) and 53.5 (2)°, respectively. The two Zr-O-Zr bridge angles are nearly linear and form a planar Zr₃O₂ co...
