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-

Geometric parameters of the title compound, C~16~H~14~O~3~, a chalcone derivative, are in the usual ranges. The C=C double bond is __trans__ configured. The molecule is essentially planar (r.m.s. deviation for all non-H atoms = 0.066 Å). The molecular conformation is stabilized by an O—H...O hydroge
