A Rh-II-Au-II bimetallic core with a direct metal-metal bond
The d(8)center dot center dot center dot d(10) heterobimetallic (RhAuI)-Au-I(tfepma)(2)((CNBu)-Bu-t)(2)Cl-2 (1) complex (tfepma = bis[bis(trifluoroethoxy)phosphino]methylamine) is oxidized by (KAuCl4)-Cl-III to give the first structurally characterized d(7)-d(9) Rh-II-Au-II singly bonded metal complex [(RhAuII)-Au-II(tfepma)(2)((CNBu)-Bu-t)(2)Cl-3](+)[(AuCl2)-Cl-I](-) (2). Complex 2 undergoes a thermal intermetal redox reaction to generate fac-Rh-III(tfepma)((CNBu)-Bu-t)Cl-3 (3) and Au-2(I,I)(tfepma)(2)Cl-2 (4).
