A novel high-nitrogen compound with an N,Nâ²-azo linkage, 4,4â²-azobis(1,2,4-triazole), has been synthesized and well characterized. The solid-state structure was determined by X-ray diffraction. The experimentally determined density and enthalpy of formation matched with theoretically computed values based on the B3LYP method. The DSC result suggests that 4,4â²-azobis(1,2,4-triazole) decomposes at a relatively high temperature (313.36 °C). By comparison with 3,3â²-azobis(1,2,4-triazole), containing a C,Câ²-azo linkage, the N,Nâ²-azo linkage was found to provide compounds with a relatively high density and high energy.
我们合成了一种具有 N,Nâ²-偶氮连接的新型高氮化合物 4,4â²-偶氮双(1,2,4-三唑),并对其进行了表征。固态结构是通过 X 射线衍射测定的。实验测定的密度和形成焓与基于 B3LYP 方法的理论计算值相吻合。DSC 结果表明,4,4â²-偶氮双(1,2,4-三唑)在相对较高的温度(313.36 °C)下分解。与含有 C,Câ²-偶氮连接的 3,3â²-偶氮双(1,2,4-三唑)相比,N,Nâ²-偶氮连接的化合物具有相对较高的密度和能量。
