(E)-3-(2,4-Dimeth­oxy­phen­yl)-1-(3,4,5-trimeth­oxy­phen­yl)prop-2-en-1-one

In the title chalcone derivative, C₂₀H₂₂O₆, the dihedral angle between the mean planes of the benzene rings is 15.77 (6)°. The H atoms of the central C=C double bond are in a trans configuration. There are a number of C—H...O interactions and a C—H...π interaction present in the crystal structure.
