Abstract: In the title compound, C18H20O8S2, the dihedral angle between the two thiophene rings is 2.33 (7)°. The methyl C atoms of the ester groups are disordered over two positions; the site-occupancy factors of the terminal methyl C atoms are 0.632 (18):0.368 (18) and 0.623 (17):0.377 (17). The molecular structure is stabilized by weak intramolecular C-HO interactions and the crystal structure is stabilized through weak intermolecular C-HO interactions.
