AbstractThe crystal structures of [NH3F]+[CF3SO3]−, [NH2F2]+[SbF6]−, and [N2F3]+[Sb3F16]− have been determined, representing the first structural characterizations of these simple fluoro‐nitrogen cations. The influences of the hybridization of the central nitrogen atom and of the number of fluorine substituents on the N−F bond lengths are evaluated for the series N2F+, N2F3+, NF2O+, NH3F+, NH2F2+, and NF4+. It is shown that the N−F bond length decreases from 1.40 Å to 1.26 Å with increasing fluorine substitution and increasing s‐character of the nitrogen atom, and that unusual N−F bond lengths reported in the previous literature are caused by disorder problems
