Comment top

The title compound was synthesized in the search for materials with non-linear optical properties (Okada et al., 1990; Ruiz et al., 2006; Yang et al., 2007). In the title compound, C16H18NO+.C10H7O2S-, the pyridinium and benzene rings in the cation make a dihedral angle of 6.01 (9)°. This cation possess trans configuration, which can be confirmed from the torsion angle C6—C7—C8—C9, -177.8 (2)°. The C7C8 group links the benzene and pyridinium rings, with a characteristic bond length of 1.329 (3) Å. These features are similar to those found in related compounds (Ruiz et al., 2006; Murugavel et al., 2009). All deviations from expected values for bond lengths are within ca. 0.05 Å. The ethoxy group has C1 and O1 atoms slightly deviated from the mean plane of the benzene ring, by 0.130 (2) and 0.015 (2) Å, respectively. The anion and cation are placed almost perpendicular each to other, the mean planes making an angle of 81.72 (6) Å.

Regarding the crystal packing, weak C—H···O hydrogen bonds and C—H···π interactions are stabilizing the crystal structure. The inter and intramolecular C—H···O interactions are formed mainly in cation-anion and anion-anion pairs. The pyridinium ring is significantly involved in the formation of C—H···O hydrogen bonds. Interestingly, there is a dimeric hydrogen bond between two symmetry-related anions (C25—H25···O3), and other hydrogen bonds exist between anions and cations (see Table 1). In addition, one C—H···π interaction is observed between the cation and the anion: C14—H14···Cgi (Cg is the centroid of ring C20/C21/C22/C24/C25/C26; symmetry code i: -1/2+x,1/2-y,1/2+z; see Table 1).

Experimental top

4-[2-(4-Ethoxy-phenyl)-vinyl-pyridinium iodide was obtained by condensation reaction between 1,4-dimethyl pyridinium iodide, which was prepared from 4-methylpyridine and methyl iodide, and 4-ethoxybenzaldehyde (all were taken in an equimolar ratio) in the presence of piperidine added as a catalyst. The solution was refluxed for 5 h, yielding the expected pyridinium salt after filtration (Okada et al., 1990). Then the iodide salt was dissolved in water (20 ml) and aqueous sodium 2-naphthalenesulfonate was added. A yellow precipitate was formed, which was filtered off and dried in an oven at 413 K for 1 h (Ruiz et al., 2006). Single crystals suitable for X-ray diffraction were obtained by successive recrystallization (three times) from a methanol/water (8:2 v/v) mixture.

Refinement top

H atoms were placed in calculated positions and allowed to ride on their parent atoms, with C—H distances in the range 0.93–0.97 Å and with Uiso(H) = 1.2Ueq(parent C) for CH and CH2 groups, and Uiso(H) = 1.5Ueq(parent C) for methyl groups.
