o-Phenylenediammonium bis(3-carboxy-4-hydroxybenzenesulfonate)
Abstract
In the title salt, C6H10N22+·2C7H5O6S−, the negative charge of the anion resides on the sulfonate group. In the crystal, the cations and anions are linked by N—H...O and O—H...O hydrogen bonds, forming a three-dimensional network. The complete dication is generated by crystallographic twofold symmetry.
