Insensitive Energetic Compounds Based on Regioisomeric Nitro-Substituted Fused Triazole

Published: Jan. 1, 2023

Two series of nitro-substituted fused triazole were prepared. All compounds have been fully characterized by IR, elemental analysis, 1H and 13C NMR DSC. Neutral a1 b1 exhibit quite different thermostabilities this trend has extended to their energetic salts, which could be explained the NBO analysis hydrogen bonds based on single-crystal parameters. The structures salts a2, a3 b3 also confirmed X-ray diffraction. NCI Hirshfeld surfaces performed further understand relationship between properties regioisomeric structures. new show good densities varying within 1.66-1.83 g cm-3, detonation velocities 7688-8461 m s-1 pressures 22.1-26.7 Gpa, are insensitive friction impact. High thermal stability (Td = 274 °C) combined with velocity (vD 8238 s-1) highlight promising application for salt b2 as a high-energy compound.
