Abstract
In the title molecule, C27H19N3O3, the imidazole and benzene rings make dihedral angles of 64.72 (4) and 64.02 (4)°, respectively, with the anthracene ring system (r.m.s. deviation = 0.043 Å). The nitro group is coplanar with the imidazole ring [dihedral angle = 1.1 (1)°]. The crystal packing is stabilized by weak π–π interactions with centroid–centroid distances of 3.7342 (10) and 3.7627 (9) Å.

Summary
Key indicators: single-crystal X-ray study; T = 298 K; mean (C–C) = 0.002 A; R factor = 0.044; wR factor = 0.127; data-to-parameter ratio = 15.5. C27H19N3O3, the imidazole and benzene rings make dihedral angles of 64.72 (4) and 64.02 (4), respectively, with the anthracene ring system (r.m.s. deviation = 0.043 A ). The nitro group is coplanar with the imidazole ring [dihedral angle = 1.1 (1)]. The crystal packing is stabilized by weak – interactions with centroid–centroid distances of 3.7342 (10) and 3.7627 (9) A.
