A novel class of energetic compounds with a N(O)=N−N fragment, [(3-nitro-1H-1,2,4-triazol-1-yl)-NNO-azoxy]furazans, were synthesized. The compounds synthesized are thermally stable (decomposition onset temperatures 147–228 °C), exhibit acceptable densities (1.77–1.80 g∙cm–3) and optimal oxygen balance (the oxidizer excess coefficients α = 0.42–0.71). Their standard enthalpies of formation (576–747 kcal∙kg–1) were determined experimentally by combustion calorimetry and these compounds have been estimated as potential components of solid composite propellants.
