Abstract
This work presents new cationic coordination complexes of antimony with the 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene (Dipp BIAN) ligand system. The fluoroantimony complexes [SbF(Dipp BIAN)][OTf]2 and [SbF2 (Dipp BIAN)][OTf] have been successfully isolated and characterized. The fluorine substituent in the Lewis acidic complex [SbF(Dipp BIAN)][OTf]2 can be selectively replaced without degradation of the Sb-Dipp BIAN interaction to give the first dicationic azido and cyano derivatives, [Sb(CN)(Dipp BIAN)][OTf]2 and [Sb(N3 )(Dipp BIAN)][OTf]2 , which have been isolated and structurally characterized.
