摘要：

Three mono- and dinuclear nickel complexes with dichalcogenolate o-carboranyl ligands were synthesized and characterized by X-ray crystallography. The reactions of Ni(COD)(2)(COD=1,5-octadiene) with [(THF)(3)LiE2)C2B10H10Li(THF)](2) (E = S, Se) in THF in the presence of air in different ratios afforded the mono- and dinuclear nickel complexes of formulae Li(THF)(4)](2)[Ni(E2C2B10H10)(2)] (E=S, la; E=Se, 1b) and [Li(THF)(4)](2)[Ni-2(E(2)CZB(10)H(10))(3)] (E=S, 2a; E=Se, 2b). In 2a, two nickel atoms are connected by one chalcogen (eta(1),eta(2)-S2C2B10H10) bridging ligand with strong metal-metal interaction. Complex of formula (PPh3)(2)Ni(S2C2B10H10).0.5THF (3a) was also obtained from the reaction of (PPh3)(2)NiCl2 and [(THF)(3)LiS2C2B10H10Li(THF)](2). (C) 2003 Elsevier B.V. All rights reserved.
