چکیده
In the title compound, C(11)H(8)O(3)S(2), the dihedral angle between the mean planes of the two thio-phene rings is 65.10 (10)°. Intra-molecular C-H⋯O inter-actions form S(6) and S(7) ring motifs. In the crystal, chains along the a axis are formed by C-H⋯O inter-actions. Adjacent chains are connected into a three-dimensional network by C-H⋯O and O-H⋯O inter-actions.
