In this paper we describe the synthesis of a series of cyclic and acyclic gold phosphine, phosphide, and phosphodiide derivatives of the primary phosphine PPhH 2 . Thus, by reacting [Au(C 6 F 5 ) x (tht)] (x ) 1, 3) with an equimolecular amount of PPhH 2 , the phosphino complexes [Au(C 6 F 5 ) x (PPhH 2 )] (x ) 1, 3) are obtained. The gold(III) complex [Au(C 6 F 5 ) 3 (PPhH 2 )] reacts with gold(I), silver(I), or gold(III) reagents in the presence of a deprotonating agent, leading to the new di-or trinuclear phenylphosphide derivatives [Au(
