Synthesis and Crystal Structure of a Tetranuclear Cu(Ⅰ) Complex with Vinyfidenebis(diphenylphosphine)
The vinylidenebis(diphenylphosphine) (vdpp) reacts with CuBr to give a tetranuclear complex, [Cu4(μ3-Br)2(μ2-Br)2(μ2-vdpp)2(CH3CN)2]·(CH3CN)2 1. The title complex has crystallo-graphically imposed centrosymmetry and presents a Cu4Br4 core with distorted stair-like structure. All copper(Ⅰ) atoms in 1 assume distorted tetrahedral coordination geometry. The distance of 2.7745(11) A between the two copper centers indicates the presence of ligand-supported Cu…Cu interactions.
