Recent Advances in the Chemistry of N₅⁺, N₅⁻ and High‐Oxygen Compounds

Abstract

Abstract An overview of our work in the areas of polynitrogen and high‐nitrogen and high‐oxygen chemistry is given. Areas of interest include the synthesis and characterization of novel polynitrogen ions, such as N 5 + and N 5 − . Efforts are discussed to combine the N 5 + cation with energetic counter‐ions, such as N 3 − , NO 3 − , ClO 4 − , B(N 3 ) 4 − and P(N 3 ) 6 − . In the area of high‐oxygen carriers, complex nitrato anions were successfully combined with tetrazolium cations to yield CO/H 2 O balanced ionic liquids of interest for liquid monopropellants.
