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

Abstract

The title compound, [ZrW(C5H5)2(C2H3O)Cl(CO)5] or [W(CO)5C(CH3)OZr(C5H5)2Cl], consists of two metal centres, with a (tungsten pentacarbonyl)oxymethylcarbene group coordinating as a monodentate ligand to the chloridozirconocene. The two halves of the molecule 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.
