Here, azo-fused dinitramino energetic compound 5,5′-dinitramino-8,8′-azo-1,2,5-oxadiazolo[3,4-e][1,2,4]triazolo[4,3-a]pyrazine (4) and its energetic salts 5–7 have been prepared. Azo-fused dinitramino compound 4 exhibits excellent detonation performance (P = 36.13 GPa, and D_v = 9126 m s^–1), which is obviously better than that of RDX (D_v = 8796 m s^–1, and P = 33.60 GPa). In addition, the thermal stability of carbonyl compound 2 (T_d = 325 °C) is similar to that of HNS (T_d = 318 °C) and 2 exhibits better energy properties. These properties indicate that azo-dinitramino compound 4 has potential as a new secondary explosive, while carbonyl compound 2 also has potential as a new type of heat-resistant explosive.
