Ethyl-enediammonium tetraaquadi-sulfatomagnesium(II)

Abstract

The title compound, [NH3(CH2)2NH 3][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 tetra-aqua- bis(sulfato-O)magnesium [Mg(SO4)2(H2O) 4]2- anions ( symmetry) and organic layers of [NH 3(CH2)2NH3]2+ cations along the crystallographic b axis. The anions, built up from tetrahedral SO 4 units and octahedral Mg(H2O)4O2 units, and the cations are linked together through N- H⋯O hydrogen bonds, forming a three-dimensional network. O- H⋯O inter-actions are also present.
