Little is known about trinitromethyl nitrotriazole (TNMNT) since the crystal structure, density, energetic performance, and thermal properties have not been determined. A detailed characterization of TNMNT and its hydrazinium and potassium salts and their potential as solid propellants and oxidizers has been established. TNMNT exhibits a high density (1.96 g cm -3 ) and positive enthalpy of formation (Δ H f = +84.79 kJ mol -1 ). TNMNT and its hydrazinium and potassium salts illustrate excellent detonation properties ( P = 34.24 to 36.22 GPa, D = 8899 to 9031 ms -1 ). TNMNT and its hydrazinium salt exhibit outstanding propulsive properties ( I sp = 247.28 to 271.19 s), and these are superior to AP ( I sp = 156.63 s) and ADN ( I sp = 202.14 s). The results suggest opening the door to utilizing TNMNT and its energetic salts in solid rocket propulsion.
