Title: Fluoro–nitrogen Cations

Journal Article · · Angewandte Chemie (International Edition)

The 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+. Here 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.
