Z.-B. Zhu, S. Gao and S. W. Ng

Abstract: In the crystal structure of the title compound, [Zn(H₂O)₆](C₆H₅O₄S)₂·2H₂O, the Zn^II atom lies on a center of inversion. The complex cation interacts with the anion and uncoordinated water molecules by O-HO hydrogen bonds, generating a three-dimensional network. The anion is disordered over two equal positions along the hydroxy-sulfonate C-C axis.
