Abstract

The use of dinuclear gold derivatives [Au(2)(? -S-S)(PR3)(2)] (S-S = benzenedithiolate, toluenedithiolate; PR3 = PPh3, PPh2Me) as S-donor ligands, with rhodium and iridium complexes [M(cod)(2)]BF4 (M = Rh, Ir; cod = cyclooctadiene) affords new heteronuclear compounds containing the {Au2M} core, with the general formulation [Au2M(?-S-S)- (cod)(PR3)(2)]BF4. One of these decomposes upon heating to give [AuIr(?-S2C6H4CH3) (cod) (PPh3)]. The crystal structure of the former and [Au2Ir(?-S2C6H4) (cod) (PPh3)(2)]BF4 have been established by X-ray diffraction, The sulfur atoms from the dithiolene ligands bridge two different metal centres.
