The reaction of 3-amino-5-nitro-1,2,4-triazole with nitrous acid produces the corresponding diazonium salt. When the diazonium salt is treated with nitroacetonitrile a subsequent condensation and cyclization reaction occurred to produced 4- amino-3,7-dinitrotriazolo-[5,1-c][1,2,4] triazine (DPX-26). X-ray crystallographic analysis shows that the DPX-26 has a density of 1.86 g/cm3 while it is calculated to have a heat of formation of 398.3 kJ/mol. DPX-26 is predicted to approach the explosive performance of RDX but displays significantly better safety properties. Oxidation of DPX-26 using hypofluorous acid produces 4-amino-3,7- dinitrotriazolo-[5,1-c][1,2,4] triazine 4-oxide (DPX-27), and is also predicted to be a high performance material with enhanced safety properties.
