Abstract

The synthesis and structural characterization of the gold antimony complex [Au₈(SbPh)₂(SbPh₂)₄(PEt ₃)₆] (1) is reported. Complex 1 can be obtained by the reaction of [AuCl(PEt₃)] with a mixture of PhSb(SiMe ₃)₂ and Ph₂(SbSiMe₃) in presence of the bidentate phosphane ligand dppm [dppm = bis(diphenylphosphanyl)methane]. Complex 1 consists of a distorted heterocubic central [Au₆Sb ₂] unit connected to two annulated five-membered rings on two opposite edges. The Au^I ions show weak aurophilic interactions and are bridged by [SbPh]^2- and [SbPh₂]^- anions. Despite the high oxidation potential of Au^I, the reaction mixtures and crystals are surprisingly stable.
