Synthesis of a new nitrogen-oxygen system, 1-nitramino-1,2,3-triazole-3-nitroimide salts

Properties and Promise of Catenated Nitrogen Systems As High-Energy-Density Materials

“…The extension of the three-nitrogen 1,2,3-triazole ring has also been achieved using two nitramide extensions on the 1- and 3-positions to give a catena- 7 energetic 187 with excellent oxygen balance. This energetic material was first prepared as the potassium salt by Shitov et al by the use of NO 2 BF 4 to nitrate the amine groups of 1,3-diaminio-1,2,3-triazole ( 152 ) (Scheme ). This material was revisited 2012 by Klapötke et al to report crystal structures of a number of salts and to investigate the role played by the alternating positive charges on neighboring nitrogen atoms on overall compound stability (Figure ).…”

Phase transition induced by an external electric field as a buffer to facilitate the initial decomposition of a series of catenated nitrogen energetic systems: a first-principles study

“…In 1989, a nitrogen-rich compound with a long nitrogen chain with seven nitrogen atoms was synthesized for the first time. 11 However, its further research was limited due to its instability, although other new compounds containing the same long nitrogen chain were synthesized in subsequent studies. 12,13 This indicates that designing and synthesizing an energetic compound with a longer nitrogen chain is a a State Key Laboratory of Explosion Science and Technology, Beijing Institute of very challenging task, and one of the difficulties that needs to be surmounted is stability.…”

Cis–Trans Isomerization and Thermal Decomposition Mechanisms of a Series of Nx (x = 4, 8, 10, 11) Chain-Catenated Energetic Crystals

“…Among these azides, the azide methane is very famous, whose nitrogen content reaches 99.3% . A new nitrogen-rich compound has been synthesized, whose structure contains a long nitrogen chain with seven nitrogen atoms. In addition, other new structures containing N 7 chains were synthesized in later studies, but these compounds were found to be extremely unstable. , Therefore, designing and synthesizing longer nitrogen chains is undoubtedly a very challenging task, and one of the difficulties is that these substances containing such long nitrogen chains have very poor stability.…”

“…Christe et al synthesized a series of polynitrogen salts, composed of N 5 + and a counterion, whose crystal structures were not reported . The structures with N 6 and N 7 chains, containing metal Fe, Pr, and K, are unstable energetic systems. , Besides, the compounds with a N 9 chain have not yet been synthesized. Considering the instability of these larger energetic systems, only the energetic crystals N 4 , N 8 , N 10 , and N 11 were selected to study in this work.…”
