Abstract: In the title compound, C₁₂H₁₀O₂S₂, molecules are linked into chains by two pairs of O-HO hydrogen bonds [HO = 1.99 (2) Å, OO = 2.759 (2) and 2.783 (2) Å and O-HO = 162 and 165 (2)°]. Four hydroxy groups are linked together via hydrogen bonds to form a four-membered ring, which acts as a supramolecular synthon in the construction of one-dimensional chains of rings.
