Abstract

The title compound, [Zr(3)(C(14)H(20)Si(2))(3)O(3)], consists of three disila-bridged zirconocene units, which are connected via an oxide ligand, forming a nearly planar six-membered ring with a maximum displacement of 0.0191 (8) Å. The compound was isolated as a by-product from a mixture of [(C(5)H(4)SiMe(2))(2)ZrCl(2)] and Li[AlH(4)] in Et(2)O.

摘要

标题化合物[Zr₃(C₁₄H₂₀Si₂)₃O₃]由三个二硅桥联的锆茂单元组成，这些单元通过一个氧化物配体相连，形成一个近乎平面的六元环，最大位移为0.0191(8) Å。该化合物是在乙醚中由[(C₅H₄SiMe₂)₂ZrCl₂]和Li[AlH₄]的混合物作为副产物分离得到的。
