23 nitrogens and only one phosphorus: The N5+ ion is combined with energetic anions in the form of N5+ [P(N3)6]− and N5+ [B(N3)4]− (see scheme), containing 91 and 96 wt %, respectively, of nitrogen. Also, the thermally unstable compound N5HF2⋅n HF is prepared by metathesis from N5SbF6 and CsHF2. Its usefulness as a reagent for the synthesis of new N5+ salts is demonstrated with the preparation of N5PF6, N5BF4, and N5SO3F.
