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.

The title compound was synthesized by heating 3-carboxy-4-hydroxybenzenesulfonic acid (0.218 g, 1 mmol) and 1,2-phenylenediamine (0.108 g, 1 mmol) in water (20 mL) for 2 hours. After evaporation the solution, dark-blue block crystals formed in high yield.
Carbon-bound H atoms were positioned geometrically (C—H = 0.93 Å), and were included in the
in the riding mode approximation, with Uiso(H) = 1.2Ueq(C). H atoms bound to O and N atoms were located in a difference Fourier map and refined with restraints [N—H and O—H = 0.85 (1) Å, with Uiso(H) values fixed at 1.5Ueq(N) and 1.5Ueq(O)].Data collection: CrystalClear (Rigaku, 2005); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

A number of proton-transfer compounds of 3-carboxy-4-hydroxybenzenesulfonic acid with Lewis bases have been widely studied because of the good crystallinity of many of the compounds (Smith et al., 2004; Wang & Wei, 2007; Meng et al., 2008; Du et al., 2008). The feature is the presence of hydrogen-bonding interactions, resulted from the aminium donor group and the sulfonate and carboxyl O-atom acceptors. There are some aniline-type proton-transfer compounds reported during the past several years. These include compounds with aniline (Bakasova et al., 1991), the 4-X-substituted anilines (X = F, Cl, Br) (Smith et al., 2005b), 3-aminobenzoic acid (Smith 2005), 4-aminobenzoic acid (Smith et al., 2005c), benzylamine (Smith et al., 2006), 1,4-phenylenediamine (Smith et al., 2005a). The present paper is concerned with the crystal structure of a new proton-transfer compound of 3-carboxy-4-hydroxybenzenesulfonic acid with 1,2-phenylenediamine as Lewis base.
In the compound, the asymmetric unit consists of one half 1,2-phenylenediaminium dication and one 3-carboxy-4-hydroxy-benzenesulfonate anion. The hydrogen atom was transferred from the sulfonic group to the amino nitrogen atom, forming an 1:2 organic salt. In the anion (Fig. 1 and Table 1), the carboxyl group is nearly coplanar with the benzene ring [the dihedral angle is 3.9 o] and there is an intramolecular hydrogen bond O3—H···O6 2.600 (3) Å involving the hydroxy group and carboxyl atom. In addition, intermolecular hydrogen bonds between a sulfonate O atom and a carboxylate O atom [O5···O4 = 2.668 (2) Å; symmetry code: 1/2-x,1/2+y,1/2-z] connect the anions through head-to-tail into a one-dmensional chain (Fig. 2 and Table 2). The protonated N atoms form hydrogen bonds with three sulfonate O atoms and one carboxyl O atom [range 2.755 (3)—3.176 (3) Å) (Fig. 3 and Table 2), forming a three-dimensional network. The network are further consolidated by π—π stacking effects between the benzene rings of anions [the inter-ring centroid distance is 3.564 (1) Å].
