Energetic potassium 3，8-dinitro（pyrazolo［5，1-c］［1，2，4］triazin-4-yl）nitramide （4） with a 3-dimensional metal-organic framework （3D EMOF） was synthesized via diazotization， cycloaddition and nitration by using 5-aminopyrazole （1） as raw material. Compound 4 was characterized and analyzed by nuclear magnetic resonance （NMR）， Fourier infrared spectroscopy （FT-IR）， mass spectrometry （MS）， single crystal X-ray diffraction （SC-XRD）， and differential scanning calorimetry （DSC）. The friction sensitivity and impact sensitivity of compound 4 were tested according to BAM standard. The detonation performance of compound 4 was predicted by EXPLO 5 software based on isodesmic reaction. Results show that the crystal of compound 4 belongs to monoclinic system， space groups P2₁/c， exhibits a 3-dimensional metal-organic framework （MOF） structure with a density of 2.021 g·cm^-3 at 150 K. Compound 4 has a thermal decomposition temperature of 203.4 ℃， a theoretical detonation velocity of 8717 m·s^-1， a theoretical detonation pressure of 33.5 GPa， a friction sensitivity of 168 N， and an impact sensitivity of <3 J.
