Abstract: In the title hydrated molecular salt, [Mg(H₂O)₆](C₁₃H₉BrNO₄S)₂·2H₂O, the Mg²⁺ ion (site symmetry $\\overline{1}$ ) adopts a near regular MgO₆ octahedral coordination geometry. In the anion, the dihedral angle between the aromatic rings is 2.5 (2)° and an intramolecular O-HN hydrogen bond generates an S(6) ring. In the crystal, the components are linked by O-HO and O-HBr hydrogen bonds.
