The use of dinuclear gold derivatives [Au 2 (μ‐S‐S)(PR 3 ) 2 ] (S‐S = benzenedithiolate, toluenedithiolate; PR 3 = PPh 3 , PPh 2 Me) as S‐donor ligands, with rhodium and iridium complexes [M(cod) 2 ]BF 4 (M = Rh, Ir; cod = cyclooctadiene) affords new heteronuclear compounds containing the {Au 2 M} core, with the general formulation [Au 2 M(μ‐S‐S)(cod)(PR 3 ) 2 ]BF 4 . One of these decomposes upon heating to give [AuIr(μ‐S 2 C 6 H 4 CH 3 )(cod)(PPh 3 )]. The crystal structure of the former and [Au 2 Ir(μ‐S 2 C 6 H 4 )(cod)(PPh 3 ) 2 ]BF 4 have been established by X‐ray diffraction. The sulfur atoms from the dithiolene ligands bridge two different metal centres.
