The N-substituted derivatives of dinitroimidazoles have been synthesized for application as energetic materials. The synthesized compounds were fully characterized by 1H 13C NMR spectroscopy and elemental analysis. Most of them were determined by single crystal X-ray diffraction. The calculated densities of the compounds range between 1.89 and 1.91 g cm−3 and the experimental densities between 1.75 and 1.84 g cm−3, as obtained by X-ray crystallographic analysis. Notably, densities of the N-substituted derivatives of dinitroimidazoles are increased when two amino groups are introduced but decreased when one amino group is introduced.
N-取代的二硝基咪唑衍生物已被合成用于作为能量材料。合成的化合物通过 1H 和 13C NMR 光谱以及元素分析进行了全面表征。大多数化合物通过单晶 X 射线衍射进行了鉴定。化合物的计算密度范围在 1.89 至 1.91 g cm−3 之间,而通过 X 射线晶体学分析获得的实验密度在 1.75 至 1.84 g cm−3 之间。值得注意的是,当引入两个氨基时,二硝基咪唑的 N-取代衍生物的密度增加;而当引入一个氨基时,密度则降低。
