The azofurazan derivatives based on the trinitroethyl functionality were synthesized in good yields. Their structures were confirmed by X-ray diffraction studies, which show favorable densities (1.82-1.87 g cm-3). Interestingly, they exhibit good thermal stability (Tdec= 159 - 230 oC), acceptable oxygen balance (-15.31% - 0) and high positive heats of formation (268-1259.5 kJ mol-1). In addition, based on the densities from gas pycnometer experiments, the donation pressures and velocities of the energetic compounds were calculated, ranging from 35.4-40.8 GPa and 8900-9486 m s-1, respectively. Furthermore, nitramine 13, having oxygen balance of zero, exhibits excellent detonation properties (ΔfHm, 1259.5 kJ mol-1; D, 9486 m s-1; P, 40.8 GPa), which could be used as high detonation performance energetic material.
