The standard enthalpies of formation of nitro-NNO-azoxy compounds including nitro-NNO-azoxybenzene (2), 3-nitro-4-{[4-(nitro-NNO-azoxy)furazan-3-yl]-NNO-azoxy}-furazan (4), and bis-4,4′-(nitro-NNO-azoxy)-3,3′-azofurazan (6), as well as those of nitro compounds including 3-nitro-4-[(4-nitrofurazan-3-yl)-NNO-azoxy]furazan (3) and 4,4′-dinitro-3,3′-azofurazan (5) were determined by combustion calorimetry. It was shown that replacement of nitro group by nitro-NNO-azoxy group in the benzene and furazan rings causes the enthalpies of formation of the nitro-NNO-azoxy compounds to increase by 49–57 kcal mol−1 (on the average, by 52 kcal mol−1 per nitro-NNO-azoxy group introduced). According to the detonation velocity and detonation pressure calculations for compounds 3–6, the energetic characteristics of nitro-NNO-azoxyfurazans 4 and 6 approach those of hexanitrohexaazaisowurtzitane (CL-20), being much better than those of nitrofurazans 3 and 5.
