1 Source of material
Some 0.2 g of 5-amino-1-methyl-4-nitroimidazole was added to 5 mL of DMF and evaporated at room temperature to give colorless block crystals. X-ray single crystal diffraction was performed on the crystal.
2 Experimental details
Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.
3 Comment
Nitroimidazole compounds are an important class of energetic materials [5], [6], [7], [8], [9], [10], [11], [12], [13], [14]. 4,5-Dinitro-1-methylimidazole is one of their representatives, which was considered as a potential carrier for melt-cast explosives [15]. The introduction of amino groups into compounds can improve their thermal stability and reduce their sensitivity [16]. In this study, the title compound was obtained by the amination of 4,5-dinitro-1-methyl-imidazole with ammonia, which is an important energetic intermediate [16].
As shown in the figure, the asymmetric unit of the title compound contains two title molecules. The bond lengths and angles within these moieties are in the expected ranges. The imidazole rings are planar and the dihedral angle of the two imidazole rings is 2.7°. The carbon atoms of the methyl group, the nitro group and the amino group are nearly coplanar with the imidazole ring. However, the hydrogen atoms of the methyl group are twist out of the imidazole ring.
