Synthesis and structure of N-heterocyclic carbene gold sulfide complexes

Abstract

The synthesis and structures of gold(I) sulfide and hydrosulfide complexes, supported by N-heterocyclic carbene (NHC) ligands are described. The trigold(I) sulfide cations, {[(ICy)Au]3(μ3-S)}+ and {[(IMes)Au]3(μ3-S)}+, terminal hydrosulfide gold(I) complex and the hydrosulfide-bridged gold(I) complex with IPr as a supporting ligand, were characterized by NMR spectroscopy and X-ray diffraction crystallography.
