IN THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(2,4-dimethoxyphenyl)-3-(3,4-dimethoxyphenyl)prop-2-en-1-one], C(19)H(20)O(5), the dihedral angle between the benzene rings is 26.88 (5)°. One of the meth-oxy groups is twisted slightly away from the plane [C-O-C-C torsion angle = -12.8 (3)°] while the others are almost co-planer [C-O-C-C torsion angles = -3.2 (3), 2.6 (3) and -3.6 (3)°]. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions. A weak intra-molecular C-H⋯O inter-action occurs.
