## Abstract magnified image Oxidation of metronidazole (**4**) with sodium dichromate yielded the corresponding 2‐(2‐methyl‐5‐nitro‐1__H__‐imidazol‐1‐yl)acetic acid (**5**) which was esterified with 1‐butanol to give butyl 2‐(2‐methyl‐5‐nitro‐1__H__‐imidazol‐1‐yl)acetate (**8**). Reaction of the l
In the title compound, C 6 H 9 N 3 O 2 Se, which is a selenol substituent derivative of metronidazole, all bond lengths and angles are normal. The imidazole ring and nitro group make a dihedral angle of 6.6 (1) , while the N-C-C-Se torsion angle is 59.5 (8) .
In the title compound, C 10 H 8 N 4 O 4 , two planar fragments, viz. the imidazole and nitrophenyl rings, are tilted at a dihedral of 57.89 (7) . The nitro groups are twisted with respect to the neighbouring ring planes; the dihedral angle is 7.0 (3) for imidazole and 9.68 (8) for benzene. The cryst
