title: Dichlorido-1κCl,3κCl-hexa-kis[1,1,2,2,3,3(η)-methyl-cyclo-penta-dienyl]di-μ(2)-oxido-1:2κO:O;2:3κO:O-trihafnium(IV).
abstract: The title compound, [Hf(3)(C(6)H(7))(6)Cl(2)O(2)], is a trinuclear mol-ecule having two (MeCp)(2)HfCl units (MeCp is methyl-cyclo-penta-dien-yl) each connected to an (MeCp)(2)Hf unit by an oxide bridge. The two Hf-O-Hf bridges are nearly linear. The geometry of the three Hf atoms is tetra-hedral (assuming the MeCp group occupies one coordination site); the O-Hf-O angle is 99.8 (5)°. One of the Cl atoms is disordered, with site occupancies of 0.61 (7) and 0.39 (7).
