3, 3′-Dinitroamino-4, 4′-azoxyfurazan (NOF) was prepared via nitration of 3, 3′-diamino-4, 4′-azoxyfurazan (AOF)as raw material using pure nitric acid. New two kinds of energetic ion salts, carbohydrazide 3, 3′-dinitroamino-4, 4′-azoxyfurazan (NOF-CBH) and aminoguanidine 3, 3′-dinitroamino-4, 4′-azoxyfurazan (NOF-AG), were synthesized via metathesis reaction with nitrogen-rich cation (CBH and AG). Their structures were characterized via NMR, IR and elemental analysis. The thermal behaviors of the compounds were studies by TG-DTG. The geometric configuration of NOF and its anion (NOF^2-) were compared and studied by quantum chemistry calculations. The detonation performances of NOF-CBH and NOF-AG were predicted. Results show that the initial decomposition temperatures of NOF-CBH and NOF-AG are 144.9 ℃ and 151.6 ℃ respectively, which are higher than 90 ℃ of NOF. The standard molar enthalpy of formation and density are 515.86 kJ·mol^-1 and 1.82 g·cm^-3 for NOF-CBH and 815.96 kJ·mol^-1 and 1.75 g·cm^-3 for NOF-AG. Their values of calculated detonation velocities are greater than 8500 m·s^-1.
