Environmentally acceptable alternatives to toxic lead-based primary explosives are becoming increasingly important for energetic materials. In this study, potassium 4,4'-bis(dinitromethyl)-3,3'-azofurazanate, comprising two dinitromethyl groups and an azofurazan moiety, was synthesized and isolated as a new energetic 3D metal-organic framework (MOF). Several attractive properties, including a density of 2.039gcm(-3), a decomposition temperature of 229 degrees C, a detonation velocity of 8138ms(-1), a detonation pressure of 30.1GPa, an impact sensitivity of 2J, and friction sensitivity of 20N make 4 a good candidate as a green primary explosive.
