摘要：
A unique zwitterionic compound consisting of functionalized pyrazolate and triazolium ions was synthesized and characterized fully. The zwitterionic compound, 3,5-dinitro-4-(3,4,5-triamino-4H-1,2,4-triazol-1-ium-1-yl)-4H-pyrazol-4-ide (CPTY, 3), exhibits superhigh heat resistance, has a decomposition temperature of 335 degrees C, and is insensitive to impact and friction. In addition, owing to its high density (1.82 g cm(-3)) and positive heat of formation (555.9 kJ mol(-1)), its detonation velocity and pressure are acceptable high at 8750 m s(-1) and 31.5 GPa, respectively. The highly attractive physicochemical and detonation properties of 3 make it promising for use as a heat-resistant explosive.
