Abstract: In the title compound, C₁₁H₈O₃S₂, the dihedral angle between the mean planes of the two thiophene rings is 65.10 (10)°. Intramolecular C-HO interactions form S(6) and S(7) ring motifs. In the crystal, chains along the a axis are formed by C-HO interactions. Adjacent chains are connected into a three-dimensional network by C-HO and O-HO interactions.
