Abstract: The title compound, [CrZr(C₅H₅)₂(C₂H₃O)Cl(CO)₅], consists of two metal centres, with a (pentacarbonylchromium)oxymethylcarbene group coordinating as a monodentate ligand to the zirconocene chloride. -Delocalization through the Zr-O-C=Cr unit is indicated by a short Zr-O distance [2.041 (3) Å] and a nearly linear Zr-O-C angle [170.5 (3)°]. Molecules are aligned with their molecular planes (through Zr, Cl, carbene and Cr) parallel to the ab plane. C-HCl interactions result in zigzag chains of molecules propagating parallel to the b axis.
