Synthesis, single crystal structure and performance of N-substituted derivatives of dinitroimidazole

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.
