Inorganic Chemistry, Journal Year: 2022, Volume and Issue: 61(43), P. 17212 - 17225

Published: Oct. 17, 2022

For the first time, highly sensitive 1-(nitratomethyl)-5H-tetrazole (1-NAMT) was synthesized, representing shortest possible 1-(nitratoalkyl)-5H-tetrazole with a combined nitrogen and oxygen content of 81.4%. Compared to its related ethyl derivative, 1-(nitratoethyl)-5H-tetrazole, it exhibits improved balance, resulting in higher detonation parameters. 1-NAMT thoroughly analyzed by single-crystal diffraction experiments accompanied elemental analysis, IR spectroscopy, multinuclear (1H, 13C, 14N) NMR measurements. The thermal behavior differential analysis supported thermogravimetric analysis. Furthermore, energetic coordination compounds (ECCs) Cu different inorganic (e.g., nitrate, chlorate, perchlorate) nitroaromatic anions picrate styphnate) were synthesized analyzed. It is shown that formation ECCs (Tdec ∼ 180 °C) suitable strategy improve rather low stability (125 °C).
