Abstract

The title compound, [ZrW(C(5)H(5))(2)(C(2)H(3)O)Cl(CO)(5)] or [W(CO)(5)C(CH(3))OZr(C(5)H(5))(2)Cl], consists of two metal centres, with a (tungsten penta-carbon-yl)oxymethyl-carbene group coordinating as a monodentate ligand to the chloridozirconocene. The two halves of the mol-ecule are related by a crystallographic mirror plane. Delocalization through the Zr-O-C=W unit is indicated by a short Zr-O distance and a nearly linear Zr-O-C angle.

摘要

标题化合物[ZrW(C₅H₅)₂(C₂H₃O)Cl(CO)₅]或[W(CO)₅C(CH₃)OZr(C₅H₅)₂Cl]由两个金属中心组成，其中一个（五羰基钨）氧甲基卡宾基团作为单齿配体与氯代二茂锆配位。分子的两半通过一个晶体学镜面相关联。通过Zr - O - C = W单元的离域作用由较短的Zr - O距离和接近线性的Zr - O - C角表明。
