Description
Summary:In the title heteroaryl chalcone derivative, C17H17NO4, the dihedral angle between the pyridine and benzene rings is 10.82 (5)°. The two methoxy groups at the meta positions are essentially coplanar with the attached benzene rings [C—O—C—C torsion angles = −0.97 (14) and 179.47 (9)°], whereas the methoxy group at the para position is twisted from the attached ring with a C—O—C—C torsion angle of −104.48 (11)°. A C—H...O close contact involving two of the methoxy groups generates an S(6) ring motif. In the crystal, molecules are linked by weak C—H...O interactions into columns along the b axis.
