sodium (2a) and potassium salt (2b) were designed and synthesized. All compounds were fully characterized. The molecular structures of 1, 1a, 1b, 2a, and 2b were confirmed by single-crystal X-ray structure analyses. It was found that 1 exhibits non-planar loose molecular stacking, while 1a, 1b, and 2b exhibit compact face-to-face layered molecular packing structures, and salt 2a exhibits compact wave-like
能量和安全是含能材料 (EM) 最受关注的两个特性。平面分子的设计和合成被认为是获得高能低灵敏度EMs的有效途径。在这项研究中,一种新的 C-N 键连接的高能双三唑化合物 3,4',5-triamine-1,3'-bi(1,2,4-triazole) ( 1 ) 及其硝酸盐 ( 1a ) 和高氯酸盐 ( 1b ),以及硝化产物 5-amino-3,4'-dinitramide-1,3'-bi(1,2,4-triazole) ( 2 ) 和相应的钠 ( 2a ) 和钾盐( 2b ) 被设计和合成。所有化合物都经过充分表征。1 , 1a , 1b的分子结构、2a和2b通过单晶 X 射线结构分析得到证实。发现1表现出非平面的松散分子堆积,而1a、1b和2b表现出紧密的面对面层状分子堆积结构,盐2a表现出紧密的波浪状堆积。研究了所有化合物的物理化学性质,例如密度、热稳定性和机械敏感性。1、1a、1b、2a和2b
