Resumen
The monodentate dithiocarbamate complexes [Au2(S2CNR2)2{μ-(PPh 2)2C=CH2}] (R = Me (1), Et (2), Bz. (3)) are obtained by reaction of [Au2CI2{PPh2)2=CH2}] with NaS2CNR2. The free sulfur atoms in complex 2 can subsequently be used to coordinate a third metal center, giving the trinuclear derivatives [Au2M(μ-S2CNEt2)2-{μ(PPh 2)2C-CH2}]X (X = CIO4, M = Au (5), Ag (6); X = PF6, M = Cu (7)). The dinuclear tricoordinate gold(I) complexes [Au2(μ-S2CNEt2){μ-(PPh2) 2C=CH2}2]CIO4 (8) and [Au2(μ-S2CNEt2){μ-(PPh2) 2C=CH2}(PPh3)2]-CIO4 (9) are obtained by reaction of [Au2(μ-S2CNEt2){μ-(PPh2) 2C=CH2}2](CIO4 (4) with (PPh2)2C=CH2 or PPh3. The former is also obtained by reaction of [Au2{μ(PPh2)2C=CH2} 2](CIO4)2 with sodium N,N-diethyldithiocarbamate (1:1). The crystal structures of complexes 2 and 8 are established by X-ray crystallography.
