Abstract

Reactions of (R₃P)AuX (X = Cl, Br, I) with [(R₃P)Au] ⁺ BF₄^-, obtained from (R₃P)AuCl and AgBF₄ in tetrahydrofuran, lead to cationic binuclear gold (I) complexes of the general formula {[(R₃P)Au]₂X}⁺ BF₄^-. A number of chloro- (R = Ph, o-Tol, Mes, Bzl, Et), bromo- (R = Ph, o-Tol, Mes) and iodo-bridged (R = Ph, Mes) complexes of this type have been isolated and iden-tilled on the basis of their analytical and spectroscopic data. The crystal structure of bis[{triphenylphosphane)gold(I)]bromonium tetrafluoroborate was determined by single-crystal X-ray diffraction. The cations contain two-coordinate bromine atoms with an Au-Br-Au angle of 96.83(3)°.
