A homoleptic arylgold(I) complex: synthesis and structure of pentanuclear mesitylgold(I)

The mesitylgold(I) complex, (AuMes)5(Mes = 2,4,6-Me3C6H2), which has a five pointed star shape, was synthesized by the reaction of AuCOCl with a tetrahydrofuran solution of MesMgBr: the Au–C bond distances range from 2.12(2) to 2.20(2)A.
