Abstract
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 ethoxy group is coplanar with the attached phenyl ring [Car—O—C—C = 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.
