Crystal structure of 2-(4-methoxyphenyl)-6-nitroimidazo[1,2-a]pyridine-3-carbaldehyde

Abstract

In the title compound, C15H11N3O4, the imidazo[1,2-a] pyridine ring system is almost planar [r.m.s. deviation = 0.028 (2) Å]. Its mean plane makes dihedral angles of 33.92 (7) and 34.56 (6)° with the methoxyphenyl ring and the nitro group, respectively. The cohesion of the crystal structure is ensured by C—H...N and C—H...O hydrogen bonds, forming layers almost parallel to the ac plane.
