The carborane-selenol [(B10H11C2)SeH] has been isolated and its anion employed as a ligand. Reaction of the ligand with [AuClL] (L = PPh3, AsPh3) (1 : 1 molar ratio) or PPN[AuCl2] (PPN = N(PPh3)2) (2 : 1 molar ratio) affords the mononuclear compounds [Au(SeC2 B10H11)L] or PPN[Au(SeC2B10H11)2], respectively. Dinuclear derivatives [Au2(SeC2B10 H11)2(μ-PP)] (PP = 1,1′-bis(diphenylphosphino) ferrocene (dppf), 1,2-bis(diphenylphosphino)ethane (dppe)) are synthesised by reaction of the ligand with [Au2Cl2(μ-PP)] or by reaction of [Au(SeC2B10H11)-(AsPh3)] with the bidentate ligand. The selenolate acts in a bridging mode in [M2(μ-SeC2B10H11) (PPh3)2]X2 (M = Au, X = ClO4; M = Ag, X = TfO), obtained by treatment of the ligand with [O{Au(PPh3)}3]ClO4 or by reaction with [Ag(TfO)(PPh3)] in 1 : 2 molar ratio, respectively. The crystal structure of [Au(SeC2B10H11)(PPh3)] has been determined by X-ray diffraction studies.
