The title compound, C26H20O5, crystallizes with two independent molecules (AandB) in the asymmetric unit, which differ primarily in the location of the –OCH3groups. In the crystal, the molecules form a layered structure parallel to (10-1) by C—H...O hydrogen-bonded networks. Adjacent layers are also linked by further C—H...O hydrogen bonds, forming a three-dimensional structure.
