1,1'-Dinitramino-5,5'-bitetrazole and 1,1'-dinitramino-5,5'-azobitetrazole were synthesized for the first time. The neutral compounds are extremely sensitive and powerful explosives. Selected nitrogen-rich salts were prepared to adjust sensitivity and performance values. The compounds were characterized by low-temperature X-ray diffraction, IR and Raman spectroscopy, multinuclear NMR spectroscopy, elemental analysis, and DTA/DSC. Calculated energetic performances using the EXPLO5 code based on calculated (CBS-4M) heats of formation and X-ray densities support the high performances of the 1,1'-dinitramino-5,5'-bitetrazoles as energetic materials. The sensitivities toward impact, friction, and electrostatic discharge were also explored. Most of the compounds show sensitivities in the range of primary explosives and should only be handled with great care!
首次合成了1,1'-二硝氨基-5,5'-联四唑和1,1'-二硝氨基-5,5'-偶氮四唑。这些中性化合物是极其敏感且威力强大的炸药。制备了选定的富氮盐以调节敏感度和性能值。通过低温X射线衍射、红外和拉曼光谱、多核核磁共振光谱、元素分析以及差热分析/差示扫描量热法对这些化合物进行了表征。基于计算得到的（CBS-4M）生成热和X射线密度，使用EXPLO5程序计算出的能量性能支持了1,1'-二硝氨基-5,5'-联四唑类作为含能材料的高性能。还研究了这些化合物对撞击、摩擦和静电放电的敏感度。大多数化合物显示出与起爆药相当的敏感度，因此处理时必须格外小心！
