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 AuI ions show weak aurophilic interactions and are bridged by [SbPh]2- and [SbPh2]- anions. Despite the high oxidation potential of AuI, the reaction mixtures and crystals are surprisingly stable.
