Abstract: The title compound, [(NH3)2(CH2)2][Fe(SO4)2(H2O)4], contains centrosymmetric [Fe(H2O)4(SO4)2]2- anions, with a coordination octahedron around iron(II) built up from four water molecules and two sulfate groups. The anions are linked by hydrogen bonds of medium strength, forming a three-dimensional framework. The linkage is reinforced by N-H
O bridges from the centrosymmetric [NH3(CH2)2NH3]2+ cations, located in the centre of the interstices.
