Abstract
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)3LiE2C2B10H 10Li(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(E2C2B 10H10)2] (E=S, 1a; E=Se, 1b) and [Li(THF) 4]2[Ni2(E2C2B 10H10)3] (E=S, 2a; E=Se, 2b). In 2a, two nickel atoms are connected by one chalcogen (η1,η 2-S2C2B10H10) bridging ligand with strong metal-metal interaction. Complex of formula (PPh 3)2Ni(S2C2B10H 10)·0.5THF (3a) was also obtained from the reaction of (PPh3)2NiCl2 and [(THF)3LiS 2C2B10H10Li(THF)]2.
