Unusual Cationic Single-Bridged Binuclear Complexes of Gold(I) and Gold(III)

Abstract
Reactions of AuXPPh3 (X being a potentially bridging ligand) with Au(OClO3)PPh3 (1:1) or with AgBF4 lead to cationic single-bridged binuclear gold(I) complexes of the [Ph3PAu-X-AuPPh3] A type (A = ClO4 or BF4). The corresponding gold(III) complexes of the [Ph3P(C6F5)2Au-X-Au(C6F5)2PPh3]A type are obtained by similar reactions of Au (A) (C6F5)2PPh3 with AuX(C6F5)2PPh3.
