Energetic salts comprised of substituted 1,2,4-triazolium and tetrazolium cations and 3,5-dinitro-1,2,4-triazolate anion were synthesized and characterized. The structure of 4,5-dimethyl-1-aminotetrazolium 3,5-dinitro-1,2,4-triazolate (16) was confirmed by X-ray analysis. Based on experimentally obtained heats of combustion, these materials have calculated heats of formation ranging from ΔHf°
= 118 (2) to 778 kJ mol−1
(10) with densities >1.5 g cm−3. Salts, 2, 4, 7, 9 and 10, fall into the ionic liquid class (mp < 100 °C).
合成并鉴定了由取代的1,2,4-三唑阳离子和四唑阳离子以及3,5-二硝基-1,2,4-三唑阴离子组成的能量盐。通过X射线分析确认了4,5-二甲基-1-氨基四唑3,5-二硝基-1,2,4-三唑(16)的结构。根据实验获得的燃烧热,这些材料的计算生成热从ΔHf°=118(2)到778 kJ mol-1(10)不等,密度>1.5 g cm-3。盐2、4、7、9和10属于离子液体类(mp<100°C)。
