In the title compound, C17H16O3, the carbonyl group is in an s-cis configuration with respect to the olefinic double bond.The dihedral angle between the two benzene rings is 2.85 (3)°.The prop-2-en-1-one bridge makes dihedral angles of 4.
77 (4) and 4.15 (4)°, respectively, with the 2-hydroxyphenyl and 4-ethoxyphenyl rings.The Building Set ethoxy group is coplanar with the attached phenyl ring [Car—O—C—C threadheaders.shop = 179.72 (5)°].
An intramolecular O—H.O hydrogen bond generates an S(6) ring motif.In the crystal structure, molecules are stacked in an antiparallel manner to form columns along the b axis.The columnar structure is stabilized by C—H.
π interactions involving the 2-hydroxyphenyl ring.
