(E)-3-(4-Eth­oxy­phen­yl)-1-(2-hy­droxy­phen­yl)prop-2-en-1-one

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-hy­droxy­phenyl and 4-eth­oxy­phenyl rings. The eth­oxy group is coplanar with the attached phenyl ring [C(ar)—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.
