Hexaaquacadmium(II) bis[4-(2-hydroxybenzylideneamino)benzenesulfonate] dihydrate

In the title compound, [Cd(H(2)O)(6)](C(13)H(10)NO(4)S)(2)·2H(2)O, the Cd atom (site symmetry ) adopts a regular octa-hedral coordination and the anion is stabilized by an intra-molecular O-H⋯N hydrogen bond. O-H⋯O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules lead to a three-dimensional network.
