Abstract: In the crystal structure of the polymeric title compound, {(C₄H₁₂N₂)[Fe(OH)(SO₄)₂]·2H₂O}_n, the anion exists as a linear chain whose two independent Fe^III atoms both occupy special positions of site symmetry. The two independent cations, which also lie on inversion sites, interact with the polyanionic chain and with the uncoordinated water molecules to form a tight-held three-dimensional network.
