22.5 J and FS: 252 N). It is worth noting that energetic salt 8 exhibits a high density of 1.97 g cm−3 and an excellent calculated detonation velocity of 9468 m s−1, and that the energetic zwitterion 5-diazonium-3-trinitromethyl-1,2,4-triazolate (14) exhibits a high density of 1.893 g cm−3 and an excellent calculated detonation velocity of 9317 m s−1, which are both superior to that of HMX (9254 m s−1)
5,5'-双(三硝基甲基)-3,3'-bi-1 H -1,2,4-三唑的离子盐和意想不到的高能两性离子5-重氮-3-三硝基甲基-1,2,4-三唑盐通过分子间和分子内复分解策略合成。5,5'-双(三硝基甲基)-3,3'-bi-1 H -1,2,4-三唑(5)与铵盐(6),肼盐(7)和羟基铵盐(8)相比较低的灵敏度(IS:22.5 J和FS:252 N)。值得注意的是,高能盐8表现出1.97 g cm -3的高密度和9468 ms -1的优良计算爆轰速度。并且,高能的两性离子5-重氮-3-三硝基甲基-1,2,4-三重氮盐(14)表现出1.893 g cm -3的高密度和9317 ms -1的出色的计算爆轰速度,两者均优于到HMX的值(9254 ms -1)。
