0In the title compound, $C_{14}H_{10}O_4S_2.0.5CH_3OH$ the molecule adopts a gauche conformation around the central $C-C$ bond. Intermolecular $O-H^{...}O$ hydrogen bonds between carboxyl groups link the molecules into zigzag chains. Between chains, the thiophene rings form \pi-\pi stacking interactions with a centroid–centroid distance of $3.98 \AA$. The methanol solvent molecule forms an $O-H^{...}O$ hydrogen bond to one carboxyl group and is disordered about a crystallographic centre of inversion.
