چکیده
In the title compound, C(17)H(16)O(3), 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-hy-droxy-phenyl and 4-eth-oxy-phenyl rings. The eth-oxy group is coplanar with the attached phenyl ring [C(ar)-O-C-C = 179.72 (5)°]. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, mol-ecules are stacked in an anti-parallel manner to form columns along the b axis. The columnar structure is stabilized by C-H⋯π inter-actions involving the 2-hy-droxy-phenyl ring.
