The reaction of 1-methyl-2-sulfanyl-1,2-dicarba-closo-dodecaborane with the gold(I) complexes [AuCl(L)] afforded the neutral thiolate derivatives [Au(SCB10H10CMe)L] (L = PPh3 1, PPh2Me 2 or AsPh3 3). Further reaction of 1 with [Au(O3SCF3)(PPh3)] gave the dinuclear species [Au2(SCB10H10CMe)(PPh3) 2][O3SCF3] 4. Another dinuclear complex, [Au2(SCB10H10CMe)2(μ-dppe)] 5, can be synthesized by reaction of [Au2Cl2(μ-dppe)] (dppe = Ph2PCH2CH2PPh2) with 2 equivalents of HSCB10H10CMe. The anionic derivatives [N(PPh3)2][Au(SCB10H10CMe)Cl] 6 and [N(PPh3)2][Au(SCB10H10CMe) 2] 7 were obtained by reaction of HSCB10H10CMe with [N(PPh3)2][AuCl2] in a 1:1 or 2:1 molar ratio, respectively. Finally, by reaction of the thiol with suitable gold(III) precursors the anionic [NBu4][Au(C6F5)3(SCB 10H10CMe)] 8 or the neutral [Au{(PPh2)2C2B9H 10}(SCB10H10CMe)2] 9 derivatives were synthesized. Complexes 1, 3 and 6 have been characterised by X-ray diffraction studies.
