Abstract

Abstract : A ditopic bipy–NHC ligand has been used to construct hetero-bimetallic complexes of the monovalent group 11 metals. Abstract : An asymmetric bipy/NHC ligand L has been used to construct Au/Au, Au/Ag and Au/Cu bimetallic complexes through prior coordination of the NHC to Au(i ) and subsequent introduction of the second group 11 metal ion at the bipy donor of the hybrid ligand. The complex [Au(κ C -L )2 ]BF4, 1, has been used as the precursor for the formation of [AuAg(κ- C Au, κ 2 - N, N ′ Ag -1 )2 ](BF4 )2, 2a, [AuCu(κ- C Au, κ 2 - N, N ′ Cu -1 )2 ](BF4 )2, 2b and [AuAu′(κ-C Au/Au′, κ 1 -N Au/Au′ -1 )2 ](BF4 )2, 3 .
