Three energetic salts of cyclo-N were synthesized via a metathesis reaction of barium pentazolate and sulfates which was driven by the precipitation of BaSO . All the energetic cyclo-N salts were characterized by single-crystal X-ray diffraction, infrared (IR), H and C multinuclear NMR spectroscopies, thermal analysis (TGA and DSC), and elemental analysis. The salts exhibit relatively good detonation performance with low sensitivities and good thermal stabilities. This new method opens the door to exploring more pentazolate anion-containing high-performance energetic materials.
通过由硫酸钡沉淀驱动的五唑钡与硫酸盐的复分解反应，合成了三种含环 -N 的高能盐。所有高能环 -N 盐均通过单晶 X 射线衍射、红外（IR）、氢和碳多核 NMR 光谱、热分析（TGA 和 DSC）以及元素分析进行了表征。这些盐表现出相对良好的爆轰性能，具有低感度和良好的热稳定性。这种新方法为探索更多含五唑阴离子的高性能含能材料打开了大门。
