The syntheses and full characterization of two new halogenated 1,1-diamino-2,2-dinitroethene (FOX-7) compounds and three halogenated azo-bridged FOX-7 derivatives are described. Some of these new structures demonstrate properties that approach those of the commonly used secondary explosive RDX (cyclo-1,3,5-trimethylene-2,4,6-trinitramine). All the compounds display hypergolic properties with common hydrazine-based fuels and primary aliphatic amines (ignition delay times of 2-53 ms). This is a new role that has yet to be reported for FOX-7 and its derivatives. Their physical and energetic properties have been investigated. All compounds were characterized by single-crystal X-ray crystallography, elemental analysis, infrared spectra, and differential scanning calorimetry. These new molecules as energetic materials and hypergolic oxidizers contribute to the expansion of the chemistry of FOX-7.

1,1-二氨基-2,2-二硝基乙烯 (FOX-7) 的新角色：卤化 FOX-7 和偶氮双 (diahaloFOX) 作为高能材料和氧化剂

描述了两种新的卤化 1,1-二氨基-2,2-二硝基乙烯 (FOX-7) 化合物和三种卤化偶氮桥接 FOX-7 衍生物的合成和完整表征。其中一些新结构表现出接近常用二次炸药 RDX（环-1,3,5-三亚甲基-2,4,6-三硝胺）的特性。所有化合物都显示出与普通肼基燃料和脂肪族伯胺一起使用的自燃特性（点火延迟时间为 2-53 毫秒）。这是 FOX-7 及其衍生物尚未报道的新作用。已经研究了它们的物理和能量特性。所有化合物均通过单晶 X 射线晶体学、元素分析、红外光谱和差示扫描量热法表征。
