| Abstract: | A planar energetic molecule with high density, 5,5′‐dinitramino‐3,3′‐azo‐1,2,4‐oxadiazole ( 4 ), was obtained by the nitration of 5,5′‐diamino‐3,3′‐azo‐1,2,4‐oxadiazole using 100 % nitric acid. In addition, selected nitrogen‐rich salts were prepared. Of them, the neutral compound 4 and its hydroxylammonium salt, 6 , were further confirmed by single‐crystal X‐ray diffraction. Physicochemical and energetic properties including density, thermal stability, and sensitivity were investigated. The energetic performance from the calculated heats of formation and experimental densities indicates that many of them have potential applications as energetic materials. |
