Abstract

Graphical abstract: A composite energetic salt (CES) based on the 3-nitramino-4-tetraolefurazan anion by pairing with the hydroxylammonium and guanidinium cations in a molar ratio of 1:1 was successfully prepared and fully characterized, which showed balanced safety and detonation performances. The synthesis of high-energy–density energetic materials usually suffers from the conflict between energy and stability. The preparation of a 3-nitramino-4-(1 H -5-tetrazol-5-yl)furazan based composite energetic salt with mixed cations was successfully achieved. The newly prepared composite energetic salt was fully characterized by IR, NMR, elemental analysis and single-crystal X-ray diffraction. Additionally, its thermal stability and sensitivities were measured and its detonation performances were calculated. The results show that this new salt has better balanced safety and detonation performances compared to its parent salts.
