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 [ SbF 2 ( 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(N 3 ) ( Dipp BIAN)][OTf] 2 , which have been isolated and structurally characterized.
