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

Abstract

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.
