Coordinative Combination of Nitroamine and Gem-Dinitromethyl with Fused Ring for Enhanced Oxygen Balances and Detonation Properties

Int J Mol Sci. 2022 Nov 18;23(22):14337. doi: 10.3390/ijms232214337.

Abstract

Oxygen balance and heat of formation are closely related to the nitrogen and oxygen content in a molecule and have a significant effect on the detonation performance of energetic materials. Here a new family of 1,2,4-triazolo [4,3-b][1,2,4,5]-tetrazine containing gem-dinitromethyl and nitroamine with high nitrogen-oxygen content was synthesized and characterized. Moreover, the structure of the guanidine salt (3) and TATOT salt (4) were confirmed by single-crystal X-ray diffraction. The nitrogen and oxygen content of ammonium salt 2 reached 82.5%, with a high density (1.805 g cm-3) and high detonation properties (D = 8900 m s-1; P = 32.4 GPa), which were similar to those of RDX.

Keywords: gem-dinitromethyl; high nitrogen-oxygen content; nitroamine; triazolo-tetrazine fused ring.
