Curious cases of 3,6-dinitropyrazolo[4,3-c]pyrazole-based energetic cocrystals with high nitrogen content: an alternative to salt formation

Abstract

Two structurally interesting 3,6-dinitropyrazolo[4,3-c]pyrazole-based energetic cocrystals were prepared and confirmed by single crystal X-ray diffraction. As novel energetic materials, these two unusual neutral acid–base complexes possess high nitrogen content, good detonation properties, and improved impact and friction sensitivities which highlight their potential energetic applications.
