Synthesis and Structure of the Hexanuclear Copper(I) Cluster Compound Cu6[μ3-S2P(OEt)2]6

Abstract

A copper(I)-dithiophosphinate cluster compound Cu₆[μ₃-S₂P(OE₂]₆ (I) was synthesized and its crystal structure characterized by X-ray crystallography. Compound I crystallizes in the triclinic system, space group Pi, and the resulting centrosymmetric geometry of the six copper atoms in the molecule is intermediate between the distorted octahedron and the chair conformation of cyclohexane. In Compound I, the two S-atoms of dithiophosphinate are coordinated to three Cu atoms, and one is monodentate to one Cu and another bridges two Cu atoms.
