Resumen: The reaction of the mixed gold(III)-silver(I) diphenylphosphide complex [Au(C6F5)2(µPPh2)2Ag]2 (1) with an equimolecular amount of [AgCl(PPh3)2] leads to the formal insertion of the latter into 1, affording the pentanuclear derivative [{Au(C6F5)2{(µ-PPh2)AgPPh3}(µPPh2)}2(µ-Ag)(µ3-Cl)] (2). Surprisingly, complex 2 is also obtained by treatment of [Au(C6F5)2- (PPh2H)2]ClO4 with [Ag(TfO)(PPh3)] (TfO ) trifluoromethanesulfonate) and AgTfO (2:2:1) in the presence of PPN(acac) (PPN ) [N(PPh3)2]+, acac ) acetylacetonate) and PPNCl. The crystal structure of 2 has been determined by X-ray diffraction studies, and it displays an unusual, perfectly planar T-frame µ3-Cl atom acting as a bridge between the three silver atoms.
