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.
通过使用100%硝酸硝化5,5'-二氨基-3,3'-偶氮-1,2,4-恶二唑制备了一种具有高密度的平面含能分子5,5'-二硝氨基-3,3'-偶氮-1,2,4-恶二唑（4）。此外，还制备了一些含氮量高的盐。其中，中性化合物4及其羟铵盐6通过单晶X射线衍射进一步得到证实。研究了包括密度、热稳定性和感度在内的物理化学和含能性能。由计算的生成热和实验密度得出的含能性能表明，它们中的许多具有作为含能材料的潜在应用。
