Eight new energetic salts based on 1-methoxy-5-nitroiminotetrazole, which was obtained by nitration of 1-methoxy-5-aminotetrazole, were synthesized. Guanidinium (5), aminoguanidinium (6), diaminoguanidinium (7), triaminoguanidinium (8), carbohydrazidinium (9), 3-amino-1,2,4-triazolium (10), 4-amino-1,2,4-triazolium (11), and 3,5-diamino-1,2,4-triazolium (12) salts were characterized by vibrational spectroscopy (IR, Raman), multinuclear spectroscopy (1H, 13C, 15N), elemental analysis, and single crystal X-ray diffraction analysis. Salts 5·1/3H2O and 7–9 crystallize in the triclinic space group P, whereas compounds 6 and 10 crystallize in the monoclinic space groups C2/c and P2(1)/n, respectively. Compound 11 is in orthorhombic group P2(1)2(1)2(1). In addition, the heats of formation (ΔHf), and detonation properties (pressure and velocity) were calculated using Gaussian 03 and EXPLO5 programs, respectively. Thermal stabilities were obtained by DSC measurements and the sensitivities toward impact and friction were determined by BAM methods.
基于1-甲氧基-5-硝基亚氨基四唑的八种新型高能盐被合成,该化合物是通过对1-甲氧基-5-氨基四唑进行硝化获得的。合成的盐包括:氨基脲盐(5)、氨基氨基脲盐(6)、二氨基脲盐(7)、三氨基脲盐(8)、碳肼基脲盐(9)、3-氨基-1,2,4-三唑盐(10)、4-氨基-1,2,4-三唑盐(11)和3,5-二氨基-1,2,4-三唑盐(12)。这些盐的特性通过振动光谱(红外光谱、拉曼光谱)、多核光谱(1H、13C、15N)、元素分析以及单晶X射线衍射分析进行了表征。盐5·1/3H2O和7–9以三斜晶系P空间群结晶,而化合物6和10则分别以单斜晶系C2/c和P2(1)/n结晶。化合物11属于正交晶系P2(1)2(1)2(1)。此外,利用Gaussian 03和EXPLO5程序分别计算了生成热(ΔHf)和爆炸特性(压力和速度)。热稳定性通过DSC测量获得,而撞击和摩擦的敏感性则通过BAM方法确定。
