In the title mol-ecule, C18H18O4, the C=C bond of the central enone group adopts a trans conformation. The relative conformation of the C=O and C=C bonds is s-cisoid. The dihedral angle between the planes of the benzene rings is 29.49 (12)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into chains along [010].
