In this paper we describe the synthesis of a series of cyclic and acyclic gold phosphine, phosphide, and phosphodiide derivatives of the primary phosphine PPhH2. Thus, by reacting [Au(C6F 6)x(tht)] (x = 1, 3) with an equimolecular amount of PPhH2, the phosphino complexes [AuC6F5) x(PPhH2)] (x = 1, 3) are obtained. The gold(III) complex [Au(C6F5)3(PPhH2)] 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(C6F5)3(μ-PPhH)Au(PR3)] (R = Ph, Me), PPN[{Au(C6F5)3)(μ-PPhH)} 2M] (M = Au, Ag). The anionic gold(III) complex PPN[{Au(C 6F5)3}2(μ-PPhH)] further reacts with similar gold(I) precursors to afford higher nuclearity pnosphodiide species, such as PPN[{AuC6F5)3} 2(μ3-PPh){Au(PPh3)}], (PPN) 2[{Au(C6F5)3}2(μ 3-PPh){Au(C6F5)}], or (PPN) 3[{(Au(C6F5)3)2(μ 3-PPh)}2-Au]. Furthermore, treatment of [Au(C 6F5)2(μ-Cl)]2 with PPhH 2 results in the formation of the cyclic trinuclear complex [AuC 6F5)2(μ-PPhH)]3, which can further react with [Au(acac)-(PPh3)] to afford the tetranuclear phosphide/phosphodiide derivative [{Au(C6F5) 2(μ-PPhH)}2-{Au(C6F5) 2(μ-PPh)Au(PPh3)}]. The crystal structures of compounds PPN[{Au(C6F5)3} 2(μ-PPhH)], [{Au(C6F5) 3}(μ3-PPh){Au(PPh3)}2], and [Au(C6F5)2 (μ3-PPhH)] 3 have been determined by X-ray diffraction methods.
