Pentacarbonyl-2κ⁵C-chlorido-1κCl-bis[1(η⁵)-cyclopentadienyl][μ₂-oxido(methyl)methylene-1:2κ²O:C]tungsten(0)zirconium(IV)

Abstract

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.
