Synthesis and structure of [Ph4P]2[Cu6(S4)3S5],a polycyclic hexanuclear copper (I)cluster with complete sulphur co-ordination

Abstract

The reaction of a methanolic Cu^I–thiolate solution with elemental sulphur yields deep-red[CU₆(S₄)₃S₅]^2–which is the first hexanuclear Cu^Icluster with the complete sulphur co-ordination; the polycyclic anion can be regarded as an inorganic analogue of a corresponding mixed thiolate-sulphide complex and thus can serve as a possible model for cu^I–thiolate sites in biological systems.
