Energetic salts based on 3-hydrazino-4-amino-1,2,4-triazole (HATr): synthesis and properties

Several novel nitrogen-rich salts of 3-hydrazino-4-amino-1,2,4-triazole (HATr) were synthesized by means of metathesis reactions or Brønsted acid-base reactions in this work. These nitrogen-rich salts were fully characterized by means of single-crystal X-ray diffraction, elemental analysis, and infrared. Their structures showed that the extensive hydrogen bonding interactions between the cations and anions formed a complex 3D network, which contributes to the high density of the salts. Some of these salts exhibited reasonable thermal stability ( T d = 168-266 °C) and good impact sensitivities (IS = 4-40 J). In addition, the detonation pressures and velocities of the energetic salts were calculated, ranging from 23.1 GPa to 32.3 GPa and 7421 m s −1 to 8455 m s −1 , respectively. The synthesized energetic salts of 3-hydrazino-4-amino-1,2,4-triazole were fully characterized with respect to their prospective use in energetic applications.
