Tetrazolyl and dinitromethyl groups with 1,2,3-triazole lead to polyazole energetic materials

A class of polyazole energetic compounds (combination of tetrazolyl, dinitromethyl and triazole) was obtained from 4,5-dicyanotriazole. All the new compounds were fully characterized by IR, NMR [ ¹ H, ¹³ C{ ¹ H}], elemental analysis, and differential scanning calorimetry (DSC). Compounds 5, 6 and 8 were further characterized with single-crystal X-ray diffraction studies. Heats of formation and detonation performances were determined using Gaussian 03 and EXPLO5 v6.01 programs, which show that 5 is a promising green primary explosive and 7 as a secondary explosive has a detonation velocity superior to 1,3,5-trinitrotriazacyclohexane (RDX).
