Abstract: The title molecule, C20H20O4, lies on an inversion center. The central alkene moiety is not coplanar with the remainder of the molecule, forming a dihedral angle of 61.61 (12)° with the O-CH2-CH2-C plane and a dihedral angle of 58.70 (11)° with the phenyl plane. The central C=C length is 1.326 (2) Å.
