In the title compound, C 24 H 22 O 4 , the centroid of the central benzene ring lies on a special position of 2/ m  site symmetry, while the terminal aromatic rings are located on a mirror plane. The central and terminal benzene rings are perpendic­ular to each other. In the crystal, the mol­ecules are connected  via  C—H⋯O hydrogen bonds into a three-dimensional polymeric structure. The network is further consolidated by a C—H⋯π inter­action.
