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 FeIII atoms both occupy special positions of \\overline{1} 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.
