title: Penta-aqua-(4,6-dihy-droxy-benzene-1,3-disulfonato-κO(1))zinc penta-hydrate.
abstract: The Zn(II) atom in the title complex, [Zn(C(6)H(4)O(8)S(2))(H(2)O)(5)]·5H(2)O, is coordinated by five water mol-ecules and an O atom of a 4,6-dihy-droxy-benzene-1,3-disulfonate dianion. The coord-ination geometry is distorted octa-hedral, with the Zn-O(sulfonate) bond relatively long compared to the Zn-O(water) bonds. The coordinated and lattice water mol-ecules inter-act with each other and with the hy-droxy groups and sulfonate ligand through O-H⋯O hydrogen bonds, generating a tightly held three-dimensional network.
