Summary: | In the title chalcone derivative, C16H16O5, the dihedral angle between the furan and benzene rings is 2.06 (17)°. The two methoxy groups at the ortho and para positions are essentially coplanar with the benzene ring [C—O—C—C angles = −1.0 (5) and 178.5 (3)°], whereas the third one at the meta position is slightly twisted [C—O—C—C = 9.6 (5)°]. In the crystal, weak C—H...O interactions link the molecules into a sheet parallel to (-102). An intermolecular π–π interaction between the furan and benzene rings is present [centroid–centroid distance = 3.772 (2) Å]. A short C...C contact [3.173 (5) Å] is also observed between neighbouring furan rings.
