Two different 1,2,3-triazole based energetic compounds, featuring with azo (-NN-) and triazene (-NN–NH-) bridge were investigated. All newly synthesized compounds were fully characterized by multinuclear NMR spectroscopy, infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Comparative study indicated that both of them are insensitive to the external mechanic stimuli, however, the other key energetic properties of azo compound (E)-1,2-bis(2-methyl-5-nitro-2H-1,2,3-triazol-4-yl)diazene(2), e.g., density, detonation velocity and pressure are superior to those of triazene compound (E)-5,5'-(triaz-1-ene-1,3-diyl)bis(2-methyl-4-nitro-2H-1,2,3-triazole) (1). This work gives a revelation on the two different types nitrogen-bridged energetic materials, especially in rarely triazene-bridge type explosives.

研究了两种不同的基于 1,2,3-三唑的含能化合物，具有偶氮 (-N N-) 和三氮烯 (-N N-NH-) 桥。所有新合成的化合物均通过多核 NMR 光谱、红外光谱、元素分析和单晶 X 射线衍射进行了充分表征。对比研究表明，它们均对外部机械刺激不敏感，但偶氮化合物 ( E )-1,2-双(2-甲基-5-硝基-2H-1,2,3 -三唑-4-基)二氮烯( 2 )，例如密度、爆速和压力均优于三氮烯化合物( E )-5,5'-(triaz-1-ene-1,3-diyl)bis (2-甲基-4-硝基-2H-1,2,3-三唑) ( 1）。这项工作揭示了两种不同类型的氮桥含能材料，尤其是在很少使用的三氮烯桥型炸药中。
