Abstract: In the crystal structure of the title polymeric complex, [Hg₂(C₁₀H₆O₆S₂)(H₂O)₄]_n, the metal atom of an H₂OHgHgH₂O unit [HgO_water = 2.124 (7) Å] is linked to the metal atom of an adjacent unit by two water molecules [HgO_water = 2.619 (7) and 2.872 (7) Å], giving rise to a polycationic chain. Adjacent chains are linked through the dianion via a weaker interaction [HgO_sulfonate = 3.062 (7) Å] to form layers. The H₂OHgHgH₂O unit, the (H₂OHg)₂ parallelogram and the dianion all lie on centres of inversion. Hydrogen bonding consolidates the layers of the structure into a three-dimensional network architecture.
