Heat-resistant explosives play an irreplaceable role in specialized applications. Two energetic metal-organic frameworks (EMOFs), potassium 4,4'-oxybis[3,3'-(5-tetrazol)]furazan and (1,2,4-triazol-3-yl)tetrazole, featuring a three-dimensional framework structure, were first synthesized characterized by chemical (1H NMR, 13C MS, IR spectroscopy, single-crystal XRD) physicochemical analyses (sensitivity toward friction, impact, electrostatic, DSC-TGA test). The new 3D EMOFs found to show high thermostability, highly positive heat of formation, suitable sensitivities. Hirshfeld surface was further analyzed order explore the effect on Their detonation properties (detonation velocity, pressure, etc.) calculated EXPLO5 program. K2NTT exhibits extremely decomposition temperatures up 361 °C; meanwhile, its performance is comparable that TATB other salts, which makes it promising heat-resistant explosive.
