Since highly nitrated nitrogen-rich heterocycles are important motifs in high energy density materials, extensive studies for the development of such novel molecules have been underway. A highly energetic moiety, 3-dinitromethyl-5-nitramino-1,2,4-triazole, which consists of a triazole ring, and nitramino and dinitromethyl groups, has been designed and synthesized. By pairing with nitrogen-rich cations, several ionic derivatives were obtained. Theoretical and experimental studies show that the hydroxylammonium salt (7) is highly dense, and has excellent detonation performance with acceptable thermal stablity and sensitivities, which are superior to those of RDX. Bang bang: Several energetic salts based on a highly nitrated triazole ring, 3-dinitromethyl-5-nitramino-1,2,4-triazole, were prepared. The hydroxylammonium salt shows promising energetic properties.
