title: Hexaaqua-nickel(II) bis-[4-(2-hydroxy-benzyl-ideneamino)benzene-sulfonate].
abstract: In the title compound, [Ni(H(2)O)(6)](C((C(13) )H(10)NO(4)S)(2), the nickel(II) atom, lying on a center of symmetry, is six-coordinated by six aqua O-atom donors. The dihedral angle between the two benzene rings is 33.1 (3)°. The crystal structure is stabilized by aqua-anion O-H⋯O hydrogen bonds. Intra-molecular O-H⋯N and C-H⋯O hydrogen-bonding inter-actions occur in the anion.
