Abstract: In the title compound, C₁₄H₁₀O₄S₂·0.5CH₃OH, the molecule adopts a gauche conformation around the central C-C bond. Intermolecular O-HO hydrogen bonds between carboxyl groups link the molecules into zigzag chains. Between chains, the thiophene rings form - stacking interactions with a centroid-centroid distance of 3.98 Å. The methanol solvent molecule forms an O-HO hydrogen bond to one carboxyl group and is disordered about a crystallographic centre of inversion.
