3 Discussion
1–Methyl-2,4,5-trinitroimidazole is an energetic compound with good performance. 5 , 6 1–Methyl-2,4,5-trinitroimidazole is obtained by nitration of 1-methyl-2,4,5-triiodoimidazole with a mixture of HNO3 and H2SO4. 7 , 8 , 9 , 10 The title compound was obtained by nitration of 1-methyl-2,4,5-triiodoimidazole with a mixture of HNO3 and H2SO4 in DMF solution.
The crystal structure of the title compound was analyzed and refined by Shelxl program. 1 , 2 , 3 , 4 As shown in the figure, the asymmetric unit contains one title molecule. The bond lengths and angles within these moieties are in the expected ranges. 11 , 12 The imidazole rings are planar, the carbon atoms of the methyl group (N1) and the methylene group (N2), the oxygen atom of the carbonyl group are nearly coplanar with the imidazole ring. However, all other atoms are twisted out of the imidazole ring.
