摘要：
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)degrees; this planarity is due in part to the presence of an intramolecular O-H center dot center dot center dot 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 center dot center dot center dot O interactions into a three-dimensional network.
