Nitrogen-rich compounds such as ammonium (1), hydrazinium (2), aminoguanidinium (3), diaminoguanidinium (4), triaminoguanidinium (5), aminonitroguanidinium (6), aminocarbonylguanidinium (7), and metforminium (8), based on a nitrogen-rich anion [CA− (N% = 32.55%, CA = cyanuric acid) and co-crystal 5-amino-1H-tetrazole based on CA (9) were synthesized by means of metathesis reactions. The crystal structures
富含氮的化合物,例如铵(1),肼(2),氨基胍(3),二氨基胍(4),三氨基胍(5),氨基硝基胍(6),氨基羰基胍(7)和二甲双胍(8)富氮阴离子[CA - (ñ%= 32.55%,CA =氰尿酸)和共晶体的5-氨基-1- ħ四唑基于CA(9)通过复分解反应的方法合成。化合物的晶体结构2,4,和9·H 2 ö通过单晶X-射线衍射测定,并通过UV-vis,FT-IR,1 H NMR,MS和元素分析充分表征。通过差热分析(DTA)和热重分析(TGA)研究了热稳定性。DTA结果表明,所有化合物均表现出较高的热稳定性。此外,通过使用B3LYP功能和6-311 ++ G **基数和Born-Haber能量循环来计算形成热。理论计算提供了高能盐的爆炸压力和速度,范围为16.88–30.71 GPa和6276.5–8392.1 ms -1, 分别。化合物的冲击敏感性通过落锤试验确定。所有化合物的不敏感碰撞敏感性均大于60
