The synthesis and structural characterization of the gold antimony complex [Au 8 (SbPh) 2 (SbPh 2 ) 4 (PEt 3 ) 6 ] ( 1 ) is reported. Complex 1 can be obtained by the reaction of [AuCl(PEt 3 )] with a mixture of PhSb(SiMe 3 ) 2 and Ph 2 (SbSiMe 3 ) in presence of the bidentate phosphane ligand dppm [dppm = bis(diphenylphosphanyl)methane]. Complex 1 consists of a distorted heterocubic central [Au 6 Sb 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 [SbPh 2 ] – anions. Despite the high oxidation potential of Au I , the reaction mixtures and crystals are surprisingly stable. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
