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

The title compound, C(13)H(10)O(4)S, 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...

Sumario:The title compound, C(13)H(10)O(4)S, 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.
