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.
