title: Potassium 4,4'-Bis(dinitromethyl)-3,3'-azofurazanate: A Highly Energetic 3D Metal-Organic Framework as a Promising Primary Explosive.
abstract: 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 2.039 g cm(-3) , a decomposition temperature of 229 °C, a detonation velocity of 8138 m s(-1) , a detonation pressure of 30.1 GPa, an impact sensitivity of 2 J, and friction sensitivity of 20 N make 4 a good candidate as a green primary explosive.
