(Received 22 September 2013; accepted 29 September 2013; online 5 October 2013)

In the title hydrated salt, C6H7N2O2+·C7H5O6S·H2O, the benzene ring of the cation makes a dihedral angle of 1.32 (19)° with the attached nitro group. In the anion, an intra­molecular O—H⋯O hydrogen bond with an S(6) ring motif is formed between the carb­oxyl and hy­droxy groups; the dihedral angle between the carb­oxyl group and the benzene ring is 8.76 (8)°. The crystal structure exhibits inter­molecular N—H⋯O, O—H⋯O, C—H⋯O, and ππ [centroid–centroid distances = 3.6634 (9) and 3.7426 (9) Å] inter­actions to form a three-dimensional network.

Comment top

In continuation of our studies of molecular compounds with non-linear optical properties which are used in optoelectronic and photonic devices (Nalwa & Miyata, 1997), we herewith report the crystal structure of the title compound (I), (Fig. 1). The title compound consists of one C6H7N2O2+ cation, one C7H5O6S- anion and a water molecule in the asymmetric unit. The geometric parameters of the title compound are comparable with the reported structures (Asiri et al., 2010; Krishnakumar et al., 2012; Sudhahar et al., 2013).

The dihedral angle between the two benzene rings (C1–C6) and (C8–C13) is 8.18 (7)°. The benzene ring (C1–C6) is planar [r.m.s. deviation = 0.0152 (17) Å] and makes a dihedral angle of 1.32 (19)° with the attached nitro group. The mean plane of carboxy group is inclined at an angle of 8.76 (8)° with the planar [r.m.s. deviation = 0.0137 (16) Å] benzene ring (C8–C13) of anion.

The crystal structure exhibits intermolecular N—H···O, O—H···O, C—H···O hydrogen bonds (Table 1 & Fig. 2) and ππ interactions [[Cg1···Cg2 = 3.7426 (9)Å, Cg1···Cg2i = 3.6634 (9) Å; (i) 1/2-x, 1/2+y, z; Cg1 and Cg2 are the centroids of the rings (C1–C6) and (C8–C13), respectively] to form a three-dimensional molecular arrangement.

Experimental top

The title compound was synthesized in ethanol by using 4-nitroaniline (6.90 g) and 5-sulfosalicylic acid dihydrate (12.711 g) in equimolar ratio. The saturated solution was allowed to evaporating slowly at room temperature. After the evaporation period of three weeks the crystals were collected and used for X-ray data collection.

Refinement top

H atoms of the water molecule were located in a difference Fourier map and were refined; the O9—H9A and O9—H9B distances were restrained to 0.82 (1) Å. All other H atoms were positioned geometrically (C—H = 0.93 Å, N—H = 0.89 Å and O—H = 0.82 Å) and refined using riding model with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(N, O).

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.
