4-Hydroxy-6-methyl-3-[3-(thiophen-2-yl)acryloyl]-2H-pyran-2-one

The title compound, C13H10O4S, crystallizes with two molecules in the asymmetric unit in which the rings make dihedral angles of 3.9 (1) and 6.0 (1)°; this planarity is due in part to the presence of an intramolecular O-H...O hydrogen bond, which generates an S(6) ring in each molecule. Both molecul...

Zusammenfassung:The title compound, C13H10O4S, crystallizes with two molecules in the asymmetric unit in which the rings make dihedral angles of 3.9 (1) and 6.0 (1)°; this planarity is due in part to the presence of an intramolecular O-H...O hydrogen bond, which generates an S(6) ring in each molecule. Both molecules represent E isomers with respect to the central C=C bond. In the crystal, molecules are linked by C-H...O interactions into a three-dimensional network.
