(E)-1-(2,5-Dimethyl-3-thien­yl)-3-(2-hy­droxy­phen­yl)prop-2-en-1-one

In the title compound, C(15)H(14)O(2)S, the dihedral angle between the aromatic rings is 8.46 –(8)°. The central enone group is planar (r.m.s. deviation = 0.0267 Å) and is oriented at a dihedral angle of 1.20 (9)° with respect to the benzene ring and at 8.27 (9)° with respect to the thio­phene group. In the crystal, the mol­ecules are linked into polymeric chains extending along the b axis due to inter­molecular O—H⋯O hydrogen bonding. An S(6) ring motif is formed due to a short intra­molecular C—H⋯O contact. C—H⋯π inter­actions involving a methyl group of the 2,5-dimethyl­thienyl group and the benzene ring are present. π–π inter­actions between the centroids of the benzene and heterocyclic rings [3.7691 (9) Å] also occur.
