Li₂(SC₆H₄) reactswith [SnR₂Cl₂] affording the dinuclearderivatives[{SnR₂(SC₆H₄)}₂](R = Me, ^tBu, Ph) (1a-c). Thereaction of these dimer derivatives with various [AuClL]breaks the tin-sulfur bonds, affording the heterobimetallic complexes[AuSnClR₂(SC₆H₄)L](L = PPh₃, AsPh₃,CH₂PPh₃) (2-4). The synthesisof[Au{SnClMe₂(SC₆H₄)}₂](5) is carriedout in a similar way. The lithiated productLi₂(SC₆H₄) can react with[AuCl(PPh₃)], giving[Au₂(SC₆H₄)(PPh₃)₂](6). The molecular structure of the complex[AuSnCl(^tBu)₂(SC₆H₄)(PPh₃)](2b) has been established by X-ray diffraction and shows atetrahedral tin center and alinear gold(I) atom bridged by the "C-S" bidentate ligand.
