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

Abstract

In the title compound, C ₁₇H ₁₆O ₄, the dihedral angle between the mean planes of the hy­droxy­phenyl and dimeth­oxy­phenyl rings is 5.9 (6)°. The mean plane of the prop-2-en-1-one group makes dihedral angles of 3.6 (0) and 2.6 (7)° with the hy­droxy­phenyl and dimeth­oxy­phenyl rings, respectively. An intra­molecular O—H⋯O hydrogen bond occurs. The crystal packing is stabilized by weak inter­molecular C—H⋯O contacts and π–π stacking inter­actions [centroid–centroid distance = 3.6571 (8) Å].
