(2E)-3-[3-(Benz-yloxy)phen-yl]-1-(2-hy-droxy-phen-yl)prop-2-en-1-one.

In the title compound, C(22)H(18)O(3), an intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif. The central benzene ring forms a dihedral angle of 64.74 (5)° with the phenyl ring and a dihedral angle of 5.58 (5)° with the terminal benzene ring. In the crystal, mol-ecules are linked into columns along the a axis via inter-molecular C-H⋯O hydrogen bonds. C-H⋯π inter-actions involving the centroid of the hy-droxy-substituted benzene ring further stabilize the crystal structure.
