The 18H23N2+·C6H5O3S−·H2O, comprises a 2-[4-(diethylamino)styryl]-1-methylpyridinium cation, a benzenesulfonate anion and a solvent water molecule. One ethyl substituent of the diethylamino group of the cation is disordered over two positions in a 0.73789 (9):0.26211 (9) ratio. The cation exists in the E configuration with respect to the C=C bond and the π-conjugated system is essentially planar with a dihedral angle of 0.82 (10)° between the pyridinium and benzene rings. The cation and anion are almost orthogonal with a dihedral angle of 86.71 (10)° between the π-conjugated system of the cation and benzene ring of the anion. In the crystal, molecules are arranged into chains along [001] and adjacent chains are linked by weak C—H⋯O interactions. The crystal is further stablilized by O—H⋯O hydrogen bonds and weak C—H⋯π interactions.

(E)-2-(4-(diethylamino)styryl)-1-methylpyridinium iodide (compound A, 0.14 g, 0.37 mmol) was prepared by a literature method (Kaewmanee et al., 2010) and then was mixed with silver (I) benzenesulfonate (Chanawanno et al., 2010) (0.10 g, 0.37 mmol) in methanol (100 ml). The mixture immediately yielded a grey precipitate of silver iodide. After stirring the mixture for 30 min, the precipitate of silver iodide was removed and the resulting solution was evaporated yielding the title compound as an orange solid. Orange block-shaped single crystals of the title compound suitable for x-ray
was recrystallized from methanol by slow evaporation of the solvent at room temperature after a few weeks, Mp. 466–468 K.All H atoms were placed in calculated positions to ride on their parent atoms, with d(O—H) = 0.97 and 1.07 Å, d(C—H) = 0.93 Å for aromatic and CH, 0.97 Å for CH2 and 0.96 Å for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the
for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups. The highest residual electron density peak is located at 1.09 Å from H14B and the deepest hole is located at 0.72 Å from S1.Data collection: APEX2 (Bruker, 2009); cell

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. |

Quaternary ammonium compounds (QACs) are relatively low toxicity and wide-ranging antimicrobial agents that are commonly used for water treatment, food industry additives and hygienic care for both medical and domestic purposes (Yabuhara et al., 2004). However, due to the long-term usage of common QACs such as benzalkonium chloride and cetylpridinium chloride, QAC resistant microorganisms have appeared. It was reported that some Staphylococcus spp. contain genes conveying resistance to this type of disinfectant (Massi et al., 2003; Soprey et al., 1968; Yabuhara et al., 2004). Therefore, we have developed the novel pyridinium QACs which can overcome this Staphylococcus-resistant phenomenon by exhibiting strong anti-methicillin-resistant Staphylococcus aureus activity and reported this discovery in our previous work (Chanawanno et al., 2010; Fun et al., 2010). The title compound was the one among many pyridinium QACs which was synthesized in our laboratory hoping for a new antibacterial drug candidate. The antibacterial activity of this compound is under investigation and its crystal structure is reported here.
Fig. 1 shows the asymmetric unit of the title compound (I) which consists of the C18H23N2+ cation, C6H5O3S- anion and one H2O molecule. The cation exists in the E configuration with respect to the C6═C7 double bond [1.337 (2) Å]. The π-conjugated system of cation (N1/C1–C13) is planar with an r.m.s deviation of 0.0215 (2) Å and the dihedral angle between the C1–C5/N1 pyridinium and the C8–C13 benzene rings is 0.82 (10)° with the torsion angle C5–C6–C7–C8 = -179.19 (17)°. One ethyl unit of the diethylamino moiety is disordered over two positions; the major component A and the minor component B (Fig. 1), with a refined site-occupancy ratio of 0.73789 (9)/0.26211 (9). The diethylamino group deviates from the attached C8–C13 ring and its conformation can be indicated by the torsion angles C11–N2–C14–C15 = 83.8 (4)°, C11–N2–C16–C17 = -95.3 (4)° for the major component A and 106.1 (7)° for the minor component B. The cation and anion are inclined to each other as indicated by the dihedral angle between the π-conjugated system of cation (N1/C1–C13) and the C19–C24 benzene ring of anion being 86.71 (10)°. The bond lengths (Allen et al., 1987) and angles in (I) are in normal ranges and comparable with those for related structures (Chanawanno et al., 2010; Kaewmanee et al., 2010).
In the crystal packing, the cations, anions and water molecules are arranged into individual chains along the [001] direction (Fig. 2). The cations are linked to the anions and water molecules in neighboring chains by C—H···O weak interactions (Table 1 and Fig. 2) whereas the anions are linked to water molecule by O—H···O hydrogen bonds (Table 1). A C—H···π interaction involving the benzenesulfonate anion was observed (Table 1).
