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 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.
