R factor = 0.045; wR factor = 0.141; data-to-parameter ratio = 26.3. In the title compound, C23H15BrO3, the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) Å] and makes a dihedral angle of 5.74 (8) with the mean plane of the bromo-substituted benzene ring. An intramolecular C— H O hydrogen bond generates an S(9) ring motif. In the crystal, molecules are linked by C—H O interactions, forming a two-dimensional network parallel to the ac plane. – stacking interactions are observed between benzene rings [centroid–centroid distances = 3.5949 (14) and 3.5960 (13) Å].
