Reaction of 5-sulfosalicylic acid with hydrazine hydrate at pH = 1 results in the formation of the title hydrated salt, 0.5N2H62+·C7H5O6S−·2H2O. The hydrazinium dications lie on centres of inversion. They are located between 3-carboxy-4-hydroxybenzenesulfonate anions, forming intermolecular N—H⋯O hydrogen bonds with sulfonate ions and water molecules of crystallisation. Further intra- and intermolecular O—H⋯O hydrogen bonds are observed in the crystal structure.

The title compound was synthesized by dissolving 5-sulfosalicylicacid dihydrate (2 mmol, 0.508 g) and hydrazine hydrate (99.98% pure; 1 mmol, 0.05 ml) in 30 ml of distilled water at pH = 1. The mixture was stirred for 4 h at ambient temperature and then filtered. The resulting clear solution was kept for three weeks in a wooden enclosure. Colourless prismatic crystals suitable for single-crystal X-ray
were grown by slow evaporation of the solvent.All non-H atoms were refined anisotropically. H atoms bonded to C atoms were positioned geometrically with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) while H atoms bonded to N and O atoms were found in difference Fourier maps and their coordinates and thermal parameters freely refined.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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. |

5-Sulfosalicylic acid, a strong organic acid with pKa = 2.85, donates its sulfonic protons to N-containing Lewis bases (Smith et al., 2004, 2005) forming organic salts (Wang, Yang et al., 2008; Wang, Yao et al., 2008; Smith & Wermuth, 2009; Hemamalini & Fun, 2010; Yin et al., 2010). Hydrazine as a diacidic base captures the H atoms of sulfonic groups from two acid molecules to form a dicationic hydrazinium salt. The molecular structure of the salt, C7H5O6S.0.5(H6N2).2(H2O), formed by the reaction of 5-sulfosalicylic acid with hydrazine hydrate at pH = 1 is shown in Fig.1 and the various types of hydrogen bonds involved in the crystal structure are reported in Table 1.
The unit cell of the crystal structure of the title compound contains eight (N2H6)2+ units located at the unit cell corners (centres of inversion) which contribute to 1/8 of the charge of each cell, two compensating 3-carboxy-4-hydroxybenzenesulfonate anions, and four isolated water molecules. The anions are held by intermolecular N—H···O hydrogen bonds in all directions with the hydrazinium ions. These N···O interactions fall in the range of 2.6813 (16)–2.7798 (16) Å. In addition, the intramolecular O6—H6···O5 hydrogen bond [D···A = 2.6074 (18) Å] and intermolecular O—H···O hydrogen bonds, O7—H7······O2 [D···A = 2.8036 (15) Å] between sulfonyl O atoms and water molecules, O4—H4···O7 [D···A = 2.6758 (16) Å] between carboxyl H atoms and isolated water molecules, and O7—H7B···O8 [D···A = 2.6754 (17) Å] between lattice water molecules, stabilize the molecular conformation and the crystal structure.
The N1—N1i distance of 1.433 (2) Å (symmetry code: (i) -x, -y, -z + 2) is in a good agreement with the values reported by Starosta & Leciejewicz (2008) and Klapotke et al. (1996). The hydrazinium ion has a staggered conformation due to the symmetry imposed by the centre of inversion located in the middle of the N—N bond.
