title: Penta-carbonyl-2κC-chlorido-1κCl-bis-[1(η)-cyclo-penta-dien-yl](μ-1-oxido-ethyl-ene-1:2κO:C)chromium(0)zirconium(IV).
abstract: The title compound, [CrZr(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)], consists of two metal centres, with a (penta-carbonyl-chromium)oxymethyl-carbene group coordinating as a monodentate ligand to the zirconocene chloride. π-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)°]. Mol-ecules are aligned with their mol-ecular planes (through Zr, Cl, carbene and Cr) parallel to the ab plane. C-H⋯Cl inter-actions result in zigzag chains of mol-ecules propagating parallel to the b axis.
