Using 5, 5′-dinitroamino-2, 2′-bi (1, 3, 4-oxadiazole) as starting material, a serials of energetic salts were synthesized. All compounds were characterized by FT-IR, multinuclear NMR spectroscopy and elemental analysis. The structures of di (3-amino-1, 2, 4-triazolium) 5, 5′-dinitroamino-2, 2′-bi (1, 3, 4-oxadiazolate)·2H₂O(9·2H₂O) and di (4-amino-1, 2, 4-triazolium) 5, 5′-dinitroamino-2, 2′-bi (1, 3, 4-oxadiazolate)(10) were further confirmed by single crystal X-ray diffraction. Their thermal stabilities were determined by differential scanning calorimetry (DSC). The detonation performance was calculated with Explo5 v6.02 software. The results show that the temperature of the thermal decomposition reaction is in the range of 146.8-239.9 ℃. The calculated detonation velocity and pressure are higher than 7693 m·s^-1 and 21.3 GPa, respectively. Their densities are from 1.683 to 1.941 g·cm^-3. The measured impact sensitivities are between 10 J and 28 J and friction sensitivities are between 160 N and 360 N, which indicated that most salts of 5, 5′-dinitroamino-2, 2′-bi (1, 3, 4-oxadiazole) are high energy-density materials with good properties.
