A solution of 2-[(E)-4-(diethylamino)styryl]-1-methylpyridinium iodide (0.13 g, 0.33 mmol) (Kaewmanee et al., 2010) in hot methanol (20 ml) was mixed with a solution of silver(I) 4-methoxybenzenesulfonate (0.10 g, 0.33 mmol) in hot methanol (20 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 a deep orange solid. Orange single crystals of the title compound suitable for X-ray structure determination were recrystallized from methanol by slow evaporation of the solvent at room temperature after a few weeks (m.p. 421–423 K).
All H atoms were positioned geometrically and allowed to ride on their parent atoms, with O—H = 0.89 and 0.99 Å, C—H = 0.93 Å for aromatic and CH and 0.96 Å for CH3 atoms. The Uiso(H) 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. One ethyl unit of the diethylamino is disordered over two sites with refined site occupancies of 0.665 (6) and 0.335 (6).

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. |

For a long time, quaternary ammonium compounds (QACs) have been used as disinfectants in both medical and domestic purposes due to their low toxicity and wide-ranging antimicrobial properties (Domagk, 1935). We have during the course of our research reported on the synthesis and antibacterial activity of pyridinium derivatives (Chanawanno et al., 2010). The title compound (I) was synthesized and tested for antibacterial activity. Our antibacterial assay showed that (I) exhibits moderate activity against Pseudomonas aeruginosa with the MIC value of 37.5 µg/ml. Herein its crystal structure is reported.
The asymmetric unit of the title compound (Fig. 1) consists of a C18H23N2+ cation, a C7H7O4S- anion and one H2O molecule. The cation exists in the E configuration with respect to the C6═C7 double bond [1.332 (2) Å] and the torsion angle C5–C6–C7–C8 = -177.25 (15)°. The cation is nearly planar with the dihedral angle between the C1–C5/N1 pyridinium and the C8–C13 benzene rings being 4.27 (8)°. One ethyl unit of the diethylamino moiety is disordered over two positions; the major component A and the minor component B (Fig. 1), with the refined site-occupancy ratio of 0.665 (6)/0.335 (6). The diethylamino moiety with the disordered ethyl unit deviated from the attached benzene ring and the disordered ethyl units point opposite to each other as indicated by the torsion angles C11–N2–C14A–C15A = -103.6 (3)° for the major component A and C11–N2–C14B–C15B = 101.7 (5)° for the minor component B. The other diethylamino moiety also deviated from its bound benzene ring with the torsion angle C11–N2–C16–C17 = -80.5 (2)° and point toward the same direction as the ethyl unit of the minor component B. The cation and anion are inclined to each other as indicated by the dihedral angles between the pyridinium and benzene rings of cation, and the sulfonate substituted benzene ring being 89.60 (8) and 89.37 (8)°, respectively. The bond lengths are in normal ranges (Allen et al., 1987) and comparable with related structures (Fun et al., 2011a,b)
In the crystal packing, the cations, anions and water molecules are linked into a network by O—H···O hydrogen bonds and C—H···O weak interactions (Fig. 2 and Table 1). π···π interactions with the centroid–centroid distances of Cg1···Cg1vii = 3.7106 (9) Å and Cg1···Cg2ii = 3.6999 (9) Å were observed; Cg1 and Cg2 are the centroids of N1/C1–C5 and C8–C13 rings, respectively.
