High density energetic salts containing nitrogen‐rich cations and the nitranilic anion were readily synthesized in high yield by metathesis reactions of sodium nitranilate 2 and an appropriate halide. All of the new compounds were fully characterized by elemental, spectral (IR, 1H, 13C NMR), and thermal (DSC) analyses. The structure of hydrazinium nitranilate (4) was also determined by single‐crystal
通过硝酸亚硝酸钠2和适当的卤化物的复分解反应,可以轻松地高收率地合成含有富氮阳离子和硝酸根阴离子的高密度含能盐。所有新化合物均通过元素分析,光谱分析(IR,1 H,13 C NMR)和热分析(DSC)进行了全面表征。还通过单晶X射线分析确定了氨基苯甲酸肼盐(4)的结构。阴离子的高对称性和氧含量使这些盐具有广泛的氢键结合能力,从而进一步导致了高密度,低水溶性和高热稳定性(T d> 200°C)的这些化合物。使用Gaussian 03和Cheetah 5.0进行理论性能计算。这些新盐的计算爆炸压力(P)在17.5 GPa(10)和31.7 GPa(4)之间,并且爆炸速度(νD)在7022 m s -1(13)和8638 m s -1(4)之间。

hydroxylammonium salt (5), all the remaining salts exhibit good thermal stabilities with decomposition temperature above 180 °C. Furthermore, the densities of salts ranged from 1.65 g cm−3 to 1.88 g cm−3. Theoretical calculations provided detonation pressures and velocities for the energetic salts within the range of 24.9–38.0 GPa and 7582.2–9072.7 m s−1, respectively.

Highly dense nitrogen‐rich ionic compounds are potential high‐performance energetic materials for use in military and industrial venues. Guanazinium salts with promising energetic anions and a family of energeticsalts based on nitrogen‐rich cations and the 6‐nitroamino‐2,4‐diazido[1,3,5]triazine anion (NADAT) were prepared and fully characterized by elemental analysis, IR spectroscopy, 1H NMR and
