摘要：

A new synthesis of cis-Me(4)N[Au(C6H4NO2 - 2)(2)Cl-2] (1) is reported, involving the reaction of [Hg(C6H4NO2 - 2)Cl] with Me(4)N[AuCl4] in the presence of Me(4)NCl. Reaction of 1 with NaOPh or with Tlacac (acac = acetylacetonate) in the presence of NaClO4 yields Na[Au(C6H4NO2 - 2)(2)(OPh)(2)] (2) or cis-[Au(C6H4NO2 - 2)(2)(O,O-acac)] (3), respectively. Complex 3 reacts with PPh(3) to give trans-[Au(C6H4NO2 - 2)(2)(C-acac)(PPh(3))] (4). Treatment of 2 in acetone with NaOH gives [Au(C6H4NO2 - 2)(2)(mu-OH)](2) (5), which is also formed when a solution of 2 in CHCl3/hexane is exposed to water. The crystal structure of 5 . 2Et(2)O shows that it is a centrosymmetric dimer with two hydroxo groups bridging two Au(C6H4NO2 - 2) moieties. The features of the structure include short Au-C bond distances (1.992(5) Angstrom, 1.995(5) Angstrom) and hydrogen bonding between the bridging OH groups and diethyl ether molecules.
