The ZnII atom in the title complex, [Zn(C6H4O8S2)(H2O)5]·5H2O, is coordinated by five water mol­ecules and an O atom of a 4,6-dihy­droxy­benzene-1,3-disulfonate dianion. The coord­ination geometry is distorted octa­hedral, with the Zn—Osulfonate bond relatively long compared to the Zn—Owater bonds. The coordinated and lattice water mol­ecules inter­act with each other and with the hy­droxy groups and sulfonate ligand through O—H⋯O hydrogen bonds, generating a tightly held three-dimensional network.
