Energetic salts based on bis‐heterocycle‐substituted 1,2,3‐triazole (HTANFT) were synthesized and characterized by 1 H and 13 C NMR spectroscopy, infrared spectroscopy, and elemental analysis. The crystal structure of neutral HTANFT ( 4 ) was confirmed through single‐crystal X‐ray diffraction. The density of 4 and its salts ranged from 1.60 to 1.83 g cm –3 , their nitrogen contents ranged from 56.4 to 65.2 % and their decomposition temperatures ranged between 187 and 236 °C. The determined sensitivities towards impact, friction and electrostatic discharge suggest that all salts are much less sensitive than 1,3,5‐trinitro‐1,3,5‐triazinane (RDX). Moreover, the detonation pressures and velocities were calculated to be 24.6 to 32.9 GPa and 7956 to 8757 m s –1 , respectively. Therefore salts 9 , 11 and 12 are potential alternatives to RDX in explosive applications.
