Salts of trinitromethyl-substituted triazoles, 5-nitro-3-trinitromethyl-1H-1,2,4-triazole and 5,5'-bis(trinitromethyl)-3,3'-azo-1H-1,2,4-triazole (5), form a new class of highly dense energeticmaterials. Single-crystal X-ray structuring supports the formation of the cocrystal of 5 with 3,5-diamino-1,2,4-triazole, which was found to be remarkably less impact-sensitive than the azo precursor. The compounds

Synthesis of trinitromethyl and dinitromethyl-substituted azoles employing a mild and efficient nitration method has been developed using a mixture of sulfuric acid and an inorganic nitrate salt XNO3, where X = NH4 +, Na+, K+. This methodology exhibits clear advantages over the more popular mixed acids nitration approach. Various nitro functionalities such as C-trinitromethyl, N-trinitromethyl, and
