Nitrophenol energetic ionic salts based on the 5,6,7,8‐tetrahydrotetrazolo[1,5‐ b ][1,2,4]triazine (TZTN, 1 ) cation and nitrophenol anions have been synthesized in high yields by neutralization reactions. All the salts were characterized by X‐ray single‐crystal diffraction technology, IR spectroscopy, elemental analysis, and DSC measurements. The heats of formation of 2 – 4 were calculated by using isodesmic reactions. The calculated detonation pressures of these salts range from 29.7 to 32.6 GPa and their detonation velocities fall between 8337 and 8613 m s –1 ; these properties make them competitive energetic materials. In addition, the sensitivities towards impact, friction, and flame were tested, and the results indicated that salts 2 and 3 have acceptable sensitivities, whereas salt 4 shows relatively high sensitivity towards impact and flame.
