Abstract
The asymmetric unit of the title compound, C4H12N22+·2C7H5O6S−·2H2O, comprises one-half of the piperazine-1,4-diium cation, which lies across an inversion centre, a 3-carboxy-4-hydroxybenzenesulfonate anion and a water molecule. An extensive network of intermolecular O—H⋯O and N—H⋯O hydrogen bonds links the cations and anions in alternating rows down the b axis.
