title: Hexaaqua-zinc(II) bis-(4-hydroxy-benzene-sulfonate) dihydrate.
abstract: The asymmetric unit of the title hydrated mol-ecular salt, [Zn(H(2)O)(6)](C(6)H(5)O(4)S)(2)·2H(2)O, contains two half-cations, two anions and two uncoordinated water mol-ecules. Both cations are completed by crystallographic inversion symmetry, generating almost regular ZnO(6) octa-hedra. In the crystal, the cations, anions and uncoordinated water mol-ecules are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network.
