Hexaaqua­magnesium bis­{4-[(5-bromo-2-hy­droxy­benzyl­idene)amino]­benzene­sulfonate} dihydrate

摘要

In the title hydrated mol­ecular salt, [Mg(H2O)6](C13H9BrNO4S)2·2H2O, the Mg2+ ion (site symmetry ) 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—H⋯N hydrogen bond generates an S(6) ring. In the crystal, the components are linked by O—H⋯O and O—H⋯Br hydrogen bonds.
