A new super heat‐resistant explosive, potassium 4‐(5‐amino‐3‐nitro‐1 H ‐1,2,4‐triazol‐1‐yl)‐3,5‐dinitropyrazole (KCPT, 1 ), featuring a three‐dimensional (3D) energetic metal–organic framework (MOF) was synthesized and fully characterized. The new 3D MOF was found to be extremely heat‐resistant, having a high decomposition temperature of 323 °C. In addition, KCPT exhibits the best calculated detonation performance ( v D =8457 m s −1 , p =32.5 GPa) among the reported super heat‐resistant explosives or energetic potassium salts while retaining a suitable impact sensitivity of 7.5 J, which makes it one of the most promising heat‐resistant explosives.
