(2E)-3-(4-Chloro-phen-yl)-1-(4-hy-droxy-phen-yl)prop-2-en-1-one.

In the title compound, C(15)H(11)ClO(2), the dihedral angle between the mean planes of the chloro-benzene and hy-droxy-benzene rings is 6.5 (6)°. The mean plane of the prop-2-en-1-one group makes an angle of 18.0 (1)° with the hy-droxy-phenyl ring and 11.5 (1)° with the chloro-phenyl ring. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds, weak C-H⋯O, C-H⋯π and π-π stacking inter-actions [centroid-centroid distances = 3.7771 (7) and 3.6917 (7) Å].
