✦ Synopsis
In the title compound, C 18 H 18 O 4 , the molecule is slightly twisted with a dihedral angle of 17.49 (5) between the two benzene rings. All of the methoxy substituents lie almost in the planes of the benzene rings to which they are attached. The crystal structure is stabilized by intermolecular C-HÁ Á ÁO, C-HÁ Á Á andinteractions.
