title: Hexaaqua-magnesium(II) bis-[4-(3-pyrid-yl)pyrimidine-2-sulfonate] tetra-hydrate.
abstract: The asymmetric unit of the title compound, [Mg(H(2)O)(6)](C(9)H(6)N(3)O(3)S)(2)·4H(2)O, contains half of a centrosymmetric cation, one 4-(3-pyrid-yl)pyrimidin-2-sulfonate anion and two solvent water mol-ecules. Inter-molecular O-H⋯O and O-H⋯N hydrogen bonds link the cations, anions and water mol-ecules into a three-dimensional supra-molecular structure. The crystal packing also exhibits inter-molecular π-π inter-actions between the aromatic rings of the anions with a centroid-centroid distance of 3.604 (2) Å.
