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).
标题化合物[Hf₃(C₆H₇)₆Cl₂O₂]是一种三核分子，具有两个(MeCp)₂HfCl单元（MeCp为甲基环戊二烯基），每个单元通过一个氧化物桥与一个(MeCp)₂Hf单元相连。两个Hf-O-Hf桥几乎呈线性。三个Hf原子的几何构型为四面体（假设MeCp基团占据一个配位位点）；O-Hf-O角为99.8 (5)°。其中一个Cl原子无序，占据率为0.61 (7)和0.39 (7)。
