For the development of safe, non-toxic and environmentally friendly gas generators, a nitrogen-rich compound 5,7-diamine-2-nitro-1,2,4-triazolo[1,5-a]-1,3,5-triazine (ANTT) was synthesized from 3,5-diamine-1,2,4-triazole in two steps. The structure of ANTT was comprehensively characterized and well investigated by X-ray diffraction. The thermal stability, detonation properties and mechanical sensitivities of ANTT were finely studied. ANTT, enjoyed with a high content of nitrogen (57.13%), as well as a high decomposition temperature of 358.5 °C, high self-accelerating decomposition temperature of 340.3 °C, high critical temperature of thermal explosion 342.2 °C, high apparent activation energy of 512.23 kJ•mol−1 and low sensitivity toward destructive mechanical stimuli (IS > 60 J; FS > 360 N), is promising candidate as gas generator.
