In the 2O)6](C6H5O4S)2·2H2O, the ZnII atom lies on a center of inversion. The complex cation interacts with the anion and uncoordinated water molecules by O—H⋯O hydrogen bonds, generating a three-dimensional network. The anion is disordered over two equal positions along the hydroxy–sulfonate C—C axis.

Sodium 3-carboxy-4-hydroxybenzenesulfonate (0.52 g, 2 mmol) was reacted with zinc carbonate (0.25 g, 2 mmol) in water. The mixture was sealed in a 50-ml Teflon-lined stainless-steel bomb and heat at 403 K for three days. The bomb was then allowed to cool naturally to room temperature. Colorless prismatic crystals were obtained. C&H elemental analysis. Calc. for C12H26O16S2Zn: C 25.93, H 4.71%; found: C 25.97, H 4.77%. The carboxyl group of sodium 3-carboxy-4-hydroxybenzenesulfonate was apparently cleaved under the hydrothermal conditions.
The aromatic ring is disordered over two positions in respect of four carbon atoms. 1,2-Related carbon-carbon distances were restrained to 1.39±0.01 Å and the 1,4-related ones to 2.78±0.01 Å. Each component ring was restrained to be nearly flat. As the disorder refined to nearly 1:1, the occupancy of the disordered atoms was set as exactly 0.5.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2U(C). The water and hydroxy H-atoms were refined with a distance restraint of N–H 0.84±0.01 Å; their temperature factors were refined.The hexaaquanickel, hexaaquacobalt and hexaaquacopper salts are not isostructural; see: Du et al. (2007); Kosnic et al. (1992); Liu & Zeng (2007).
