摘要

Two energetic compounds, 4,8-dinitraminodifurazano[3,4- b , e ]pyrazine ( 1 ) and its potassium-based energetic metal–organic framework (E-MOF) ( 2 ), were prepared, and their crystal structures were confirmed by single-crystal X-ray diffraction analysis. Compound 1 cocrystallizes with water molecules and shows a three-dimensional (3D) sandwich-like supramolecular structure, which is rare in the known energetic organic compounds. Compound 2 has a pillared layered structure with a pcu topology. The layered structure in the 3D framework featuring sql topology was constructed from inorganic chains {K_(2)O} and nitroamine groups. The crystal density of 2 is up to 2.114 g cm~(–3). This potassium-based E-MOF shows high thermal stability, high detonation velocity, and high impact and friction sensitivities, which make it a potential high-performing primary explosive.
