A RhII-AuII bimetallic core with a direct metal-metal bond.
The d8...d10 heterobimetallic RhIAuI(tfepma)2(CNtBu)2Cl2 (1) complex (tfepma = bis[bis(trifluoroethoxy)phosphino]methylamine) is oxidized by KAuIIICl4 to give the first structurally characterized d7-d9 RhII-AuII singly bonded metal complex [RhIIAuII(tfepma)2(CNtBu)2Cl3]+[AuICl2]- (2). Complex 2 undergoes a thermal intermetal redox reaction to generate fac-RhIII(tfepma)(CNtBu)Cl3 (3) and Au2I,I(tfepma)2Cl2 (4).
