Crystal, molecular, and electronic structure of [Ta2Cl4(µ-Cl)4(PMe3)4]: a metal–metal single bond between eight-co-ordinate tantalum atoms
Abstract
The crystal structure of the title complex shows an MCl4M bridge across a weak Ta–Ta interaction and eight-fold co-ordination about each metal centre; an electronic structure calculation supports the existence of a σ metal–metal bond.
