Complexes Q[Au(R)Cl] react with H2S in the presence of diethylamine to give the corresponding organo(hydrosulfido)gold(I) complexes Q[Au(R)(SH)] [R = C6F5, Q = Ph3P=N=PPh3 = PNP, Bu4N; Q = PNP, R = C6H4NO2-2, C6H2(NO2)3-2,4,6]. Under the same reaction conditions, Me4N[Au(C6F5)Cl] gives the bridging organo(μ3-sulfido)gold(I) complex (Me4N)2[{Au(C6F5)} 3(μ3-S)], whereas Et4N[Au(C6F5)Cl] gives Et4N[Au(C6F5)SH] or (Et4N)2[{Au(C6F5)} 3(μ3-S)] depending on the workup procedure. The crystal structure of Et4N-[{Au(C6F5)}3(μ 3-S)]·0.5MeC(O)Et has been determined. The Au?Au contacts are 3.1844, 3.2773, and 3.4772 A?, with corresponding angles 86.68, 90.31, and 97.65° at sulfur.
