Abstract: The title compound, [NH₃(CH₂)₂NH₃][Mg(SO₄)₂(H₂O)₄], was synthesized by the slow evaporation method. Its crystal structure can be described as an alternate stacking of inorganic layers of tetraaquabis(sulfato-O)magnesium [Mg(SO₄)₂(H₂O)₄]^2- anions ( $\\overline1$ symmetry) and organic layers of [NH₃(CH₂)₂NH₃]²⁺ cations along the crystallographic b axis. The anions, built up from tetrahedral SO₄ units and octahedral Mg(H₂O)₄O₂ units, and the cations are linked together through N-HO hydrogen bonds, forming a three-dimensional network. O-HO interactions are also present.
