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

Abstract

In the title compound, C15H14O2S, 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.
