In the title molecule, C18H18O4, the C=C bond of the central enone group adopts a trans conformation. The relative conformation of the C=O and C=C bonds is s-cisoid. The dihedral angle between the planes of the benzene rings is 29.49 (12)°. In the crystal, weak C—H
O hydrogen bonds link the molecules into chains along [010].

In the title molecule, C17H11BrN2, the planes of the anthracene ring system [maximum deviation from the mean plane = 0.036 (3) Å] and the imidazole ring form a dihedral angle of 85.14 (14)°. In the crystal, weak C—HN and C—HBr hydrogen bonds link the molecules into double chains propagating along [01-1]. In addition, π–π stacking interactions between pairs of benzene rings are observed, with centroid–centroid distances of 3.7968 (17) and 3.8496 (16) Å.
