Abstract: 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...[pi] interaction present in the crystal structure.
