Abstract

In the title molecule, C26H16BrN3O3, the anthracene and benzene mean planes make dihedral angles of 63.79 (2) and 14.67 (2)°, respectively, with the plane of the imidazole ring. In the crystal structure, weak intermolecular C—H...O hydrogen bonds link molecules to form centrosymmetric dimers. Weak π–π stacking interactions, with centroid–centroid distances of 3.779 (2) and 3.826 (2) Å, supply additional stabilization. The crystal packing also exhibits short intermolecular contacts between the nitro groups and Br atoms [Br...O = 3.114 (2) Å].
