The fluoro(perfluoroalkylnitrile)noble-gas(II) cations, RFCN–NgF+(Ng = Kr or Xe; RF= CF3, C2F5, n-C3F7), and the fluoro(trifluoro-s-triazine)xenon(II) cation, s-C3F3N2N–XeF+; novel noble gas–nitrogen bonds

Abstract

Three novel examples of Kr–N bonds derived from perfluoroalkylnitriles, the R_FCN–KrF⁺ cations, and their xenon analogues R_FCN–XeF⁺(R_F= CF₃, C₂F₅, n-C₃F₇), have been prepared and characterized in BrF₅ solvent by ¹⁹F and ¹²⁹Xe n.m.r. spectroscopy; the Xe–N bonded cation s-C₃F₃N₂N–XeF⁺, synthesized as the AsF₆^– salt, is stable at room temperature and has been fully characterized by ¹²⁹Xe and ¹⁹F n.m.r. and Raman spectroscopy.
