The asymmetric unit of the title compound, C 24 H 22 O 4 , contains one half-mol­ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent mol­ecules are linked through C—H⋯O inter­actions, forming a sheet structure parallel to the  bc  plane. The sheets are stacked along the  a  axis  via  π–π inter­actions formed between the terminal benzene rings [centroid–centroid separation = 3.7276 (6) Å].
