In the centrosymmetric title compound, C12H10O2S2, the alkyl chains adopt a fully extended all-trans conformation with respect to the C(thiophene)—C bond. The non-H atoms of the molecule are nearly planar, with a maximum deviation of 0.063 (2) Å from the mean plane of the constituent atoms. In the crystal, symmetry-related molecules are linked via pairs of C—H...π contacts [H–centroid distances of the thiophene units = 2.79 (9) and 2.82 (4) Å], in turn interdigitating with each other along the bc plane, thus leading to an interwoven two-dimensional network.
