Dichlorido-1κCl,3κCl-hexa-kis-[1,1,2,2,3,3(η⁵)-cyclo-penta-dien-yl]di-μ₂-oxido-1:2κ²O:O;2:3κ²O:O-trizirconium(IV).

The title compound, [Zr₃(C₅H₅)₆Cl₂O₂], exists as discrete mol-ecules possessing a series of three Cp(2)Zr units (Cp is cyclo-penta-dien-yl) bridged by oxide ligands and end-capped by chloride ligands. The Cp planes in the central and terminal zirconocene units form dihedral angles of 53.3 (2) and 53.5 (2)°, respectively. The two Zr-O-Zr bridge angles are nearly linear and form a planar Zr₃O₂ core. The mol-ecule bears C2 symmetry with the central Zr atom lying on a crystallographic twofold axis.
