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 °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.

具有杂环离子的耐热性炸药的两性离子化合物

合成了一种独特的两性离子化合物，该化合物由官能化的吡唑酸盐和三唑鎓离子组成，并进行了充分表征。两性离子化合物3,5-二硝基-4-（3,4,5-三氨基-4H-1,2,4-三唑-1-基-1-基）-4H-吡唑-4-酯（CPTY，3），表现出极高的耐热性，分解温度为335°C，并且对冲击和摩擦不敏感。另外，由于其高密度（1.82g cm ^-3）和正形成热（555.9kJ mol ^-1），其爆轰速度和压力分别在8750m s ^-1和31.5GPa时是可接受的高。的极具吸引力的物理化学和爆轰性能3使其有希望用作耐热炸药。
