Resumen

Li2(SC6H4) reacts with [SnR2Cl2] affording the dinuclear derivatives [{SnR2(SC6H4)}2] (R = Me, tBu, Ph) (1a-c). The reaction 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 synthesis of [Au{SnClMe2(SC6H4)}2] (5) is carried out in a similar way. The lithiated product Li2(SC6H4) can react with [AuCl(PPh3)], giving [Au2(SC6H4)(PPh3)2] (6). The molecular structure of the complex [AuSnCl(tBu)2(SC6H4)(PPh 3)] (2b) has been established by X-ray diffraction and shows a tetrahedral tin center and a linear gold(I) atom bridged by the "C-S" bidentate ligand.
