1-(2-Methyl-5-nitro-1H-imidazol-1-yl)propan-2-yl acetate

Abstract

In the title compound, C9H13N3O4, an ester of the anti-infection drug secnidazole, the dihedral angle between the nitroimidazole mean plane (r.m.s. deviation = 0.028 Å) and the pendant acetate group is 43.17 (11)°. In the crystal, inversion dimers linked by pairs of C—H...O interactions generateR22(10) loops and further C—H...O hydrogen bonds link the dimers into [100] chains. Weak aromatic π–π stacking interactions with a centroid–centroid distance of 3.7623 (11) Å are also observed.
