In the title hydrated salt, C15H16NO2+·C6H4BrO3S·H2O, the cation exists in an E conformation with respect to the ethenyl bond and is almost planar, with a dihedral angle of 2.62 (12)° between the planes of the pyridinium and benzene rings. The meth­oxy substituent deviates slightly from the plane of its attached benzene ring [Cmeth­yl—O—C—C torsion angle = −11.6 (6)°]. In the crystal, the cations, anion and water mol­ecules are linked together into chains along [010] by O—H⋯O hydrogen bonds and weak C—H⋯O inter­actions. There is a short Br⋯O contact [3.029 (2) Å]. The crystal structure also features C—H⋯π inter­actions involving the benzene ring of the anion.

The stilbene scaffold is a basic element for a number of biologically active natural and synthetic compounds. Stilbene-based compounds are extensively present in nature and have attracted chemists and biologists because of their wide range of biological activities, acting as antibacterial (Chanawanno et al., 2010), anticancer (Belluti et al., 2010) and antioxidant (Frombaum et al., 2012) agents. In addition, some stilbenes also exhibit non-linear optical (Ruanwas et al., 2010) and fluorescent properties (Li et al., 2013). They are also generally used in the manufacturing industry as whitening agents (Hussain et al., 2009). Due to these interesting properties, the title pyridinium-stilbene (I) was synthesized. We report herein the synthesis and crystal structure of (I).

The asymmetric unit of (I) consists of a C15H16NO2+ cation, a C6H4BrSO3- anion and a H2O molecule (Fig. 1). All bond lengths (Allen et al., 1987) and angles in both the cation and anion are normal and compare well with those found in closely related structures (Chanawanno et al., 2009; Fun et al., 2011; Jindawong et al., 2005). The cation exists in an E configuration with respect to the C13 C14 double bond [1.326 (5) Å] and the C12—C13—C14—C15 torsion angle is 179.3 (3)°. The cation is essentially planar with a dihedral angle between the pyridinium and benzene rings of the cation of 2.62 (12)°. The hydroxy group lies close to the plane of the C7···C12 benzene ring whereas the methoxy group is slightly twisted from this plane with a C21–O5–C9–C10 torsion angle of -11.6 (6)°. The benzene ring of the 4-bromobenzenesulfonate anion makes dihedral angles of 80.35 (15) and 78.37 (15)° with pyridinium and benzene rings of the cation, respectively.

In the crystal packing (Fig. 2), intermolecular O—H···O hydrogen bonds form between the water molecule (O1W) and the O3 (sulfonate), O4 (hydroxy) and O5 (methoxy) atoms, and between the hydroxy substituent (O4) and the water molecule (O1W) (Table 1). Atoms O1 and O4 are involved in weak intermolecular C—H···O interactions (Table 1). The cations, anions and water molecules are linked into chains along [0 1 0] through these O–H···O and weak C—H···O hydrogen bonds (Fig. 2 and Table 1). The crystal structure is further stabilized by C—H···π interactions involving the centroid of the benzene ring of the cation (Table 1). A short Br···O contact [3.029 (2) Å; symmetry code +x, -1+y, z] also forms between adjacent anions.

Experimental top

First of all, 1-methyl-4-[(E)-2-(3-hydroxy-4-methoxyphenyl)ethenyl]pyridinium iodide (compound A) was prepared by mixing a solution (1:1:1 molar ratio) of 1,4-dimethylpyridinium iodide (2.98 g, 12.68 mmol), isovanillin (1.96 g, 12.86 mmol) and piperidine (1.09 g, 12.80 mmol). The resulting solution was refluxed for 3 h under a nitrogen atmosphere. The solid which formed was filtered, washed with diethylether and recrystallized from methanol, to give brown crystals of compound A (3.99 g, 85% yield Mp. 503-504 K). Thereafter, the title compound was synthesized by mixing a solution of compound A (0.21 g, 0.58 mmol) in hot methanol (45 ml) and a solution of silver (I) 4-bromobenzenesulfonate (Jindawong et al., 2005), (0.20 g, 0.58 mmol) in hot methanol (40 ml). The mixture yielded a yellow solid of silver iodide immediately. After stirring the mixture for 20 min, the precipitate of silver iodide was removed and the resulting yellow solution was evaporated to yield the title compound as a yellow solid (0.27 g, 94% yield). Yellow needle-shaped single crystals of the title compound suitable for x-ray structure determination were recrystalized from ethanol/methanol (1:1 v/v) by slow evaporation of the solvent at room temperature over several days, Mp. 511–512 K.

Refinement top

Hydroxy and water H atoms were located in difference maps and refined isotropically. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C—H) = 0.93 Å for aromatic and CH, and 0.96 Å for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
