D(8)中心点d(10)异双金属(RhAuI)-Au-I(Tfepma)(2)((CnBu)-Bu-t)(2)Cl-2(1)配合物(tfepma=bis[bis(trifluoroethoxy)phosphino]methylamine))被(KAuCl4)-Cl-III氧化得到第一个结构表征的d(7)-d(9)Rh-II-Au-II单键金属配合物[(RhAuII)-Au-II(Tfepma)(2)(CNBu)-Bu-t](2)氯离子](+)[(AuCl2)-氯离子](-)(2)。配合物2通过热金属间氧化还原反应生成fac-Rh-III(Tfepma)((CNBu)-Bu-t)Cl3(3)和Au-2(i，i)(Tfepma)(2)Cl2(4)。
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).
