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


ABSTRACT: The title compound, [Zr?(C?H?)?Cl?O?], 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 Zr?O? core. The mol-ecule bears C2 symmetry with the central Zr atom lying on a crystallographic twofold axis.

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. ...[more]
