title: Hexaaqua-cobalt(II) bis-[4-(2-hydroxy-benzyl-ideneamino)-benzene-sulfonate].
abstract: In the cation of the title compound, [Co(H(2)O)(6)](C(13)H(10)NO(4)S)(2), the Co atom lies on a centre of symmetry and its coordination geometry is octahedral. The crystal structure is stabilized by water-anion O-H⋯O hydrogen bonds. An intra-molecular O-H⋯N hydrogen bond occurs in the anion.
