4]triazolo[4,3-b]pyridazine-3-oxide, were synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, NMR, and IR spectroscopy. Both energetic compounds exhibit densities of 1.773 and 1.939 g·cm–3 for 2 and 3, respectively. The energetic properties were calculated based on the density and the heat of formation. They possess a good detonation performance (Dv: 8664 m·s–1 for 2, 8817 m·s–1
稠环含能材料是一类特殊的含有两个或多个环的π共轭结构,近年来被认为是一种潜在的高能量密度能源。在目前的工作中,设计了一种新的三环稠合高能骨架[1,2,5]恶二唑并[3,4- d ][1,2,4]三唑并[4,3 - b ]哒嗪-3-氧化物,并合成的。两种典型化合物,4-叠氮基-[1,2,5]恶二唑并[3,4- d ][1,2,4]三唑并[4,3 - b ]哒嗪-3-氧化物和4-氨基-[1 ,2,5]恶二唑并[3,4- d ][1,2,4]三唑并[4,3- b] pyridazine-3-oxide,被合成并通过单晶 X 射线衍射、元素分析、NMR 和红外光谱进行表征。两种高能化合物的2和3密度分别为 1.773 和 1.939 g·cm –3。能量特性是根据密度和形成热计算的。它们具有良好的爆轰性能(D v : 8664 m·s –1 for 2 , 8817 m·s –1 for 3 ; P
