Abstract

The centroid of the central aromatic ring of the title mol-ecule, C(24)H(22)O(4), is located on an inversion center. The dihedral angle between the central and terminal benzene rings is 75.00 (7)°. In the crystal, mol-ecules are linked through C-H⋯O hydrogen bonds into chains along [121]. The chains are connected into layers via C-H⋯π inter-actions.
