Crystal structures and properties of high-nitrogen energetic salts based on (Z)-1,1-diamino-2-nitro-2-(1H-tetrazol-5-yl)ethene

Three energetic salts (2, 3, and 5) based on (Z)-1,1-diamino-2-nitro-2-(1H-tetrazol-5-yl)ethene (1) were designed and prepared. All of them were fully characterized by NMR spectroscopy, IR spectroscopy, and elemental analysis. Their structures were further supported by single-crystal X-ray diffraction analysis. The detonation performances were calculated by using EXPLO5 software (D-v: ranging from 8580 m s(-1) to 8810 m s(-1), P: ranging from 24.1 GPa to 26.1 GPa). Additionally, these energetic salts showed good thermal stabilities ranging from 197 degrees C to 240 degrees C. Their mechanical sensitivities toward friction (FS) and impact (IS) were measured, which exhibited relatively insensitive characteristics. These properties make them promising energetic materials for future applications.
