A new symmetric compound 3,5-bis(3-amine-4H-1,2,4-triazole)-1H-pyrazole and a series of corresponding energetic salts 5–9 were synthesized. All the new compounds were fully characterized by spectroscopy (IR, NMR, and elemental) analyses and differential scanning calorimetry (DSC). Compound 6 was further investigated by X-ray crystal-structure analysis. Various performance tests of all the compounds, such as density, thermal behavior, mechanical sensitivity and detonation property, were tested. All the target compounds showed relatively positive calculated heat of formation (24.9 to 2396.4 kJ mol−1), good mechanical sensitivity (IS > 24 J, FS > 280 N) and acceptable detonation property (D > 7400 m s−1, P > 19.5 GPa). In particular, energetic salt 9 exhibits prominent detonation property (D > 8964 m s−1, P > 37.1 GPa) and excellent sensitivity (IS > 40 J, FS > 360 N), which show its potential application prospects as a new high energy insensitive material.
