(E)-1-(2,5-Dimethyl-3-thien-yl)-3-(2-hy-droxy-phen-yl)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†à ) 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 thio-phene group. In the crystal, the mol-ecules are linked into polymeric chains extending along the b axis due to inter-molecular O-H⋯O hydrogen bonding. An S(6) ring motif is formed due to a short intra-molecular C-H⋯O contact. C-H⋯π inter-actions involving a methyl group of the 2,5-dimethyl-thienyl group and the benzene ring are present. π-π inter-actions between the centroids of the benzene and heterocyclic rings [3.7691†(9)†à ] also occur.
