In the title molecular salt, C18H22NO+·C7H7O3S−, the dihedral angle between the aromatic rings in the cation is 10.00 (9)°; its alkyl side chain adopts an extended conformation. In the crystal, weak C—H⋯O and π–π [centroid–centroid distance = 3.7658 (17) Å] interactions link the components, generating a three-dimensional network.

The 4-butoxy-4'-N'-methyl stilbazolium tosylate was synthesized by the condensation reaction. The stoichiometric amount of reagents 4-picoline (4.65 g, 5 mmol), methyl p-toluenesulfonate (9.31 g, 5 mmol), and p-butoxybenzaldehyde (8.64 ml, 5 mmol) were refluxed 20 hours in the presence of piperidine. Colourless blocks of (I) were grown by slow evaporation of a methanol solution.
H atoms were positioned geometrically and refined using riding model with C-H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for CH, C-H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for CH2, C-H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for CH3. H atoms for C20 and C23 were found from the difference Fourier map and C20-H20 and C23-H23 distances were restrained to 0.93 (1)Å.
In continuation of our studies of molecular compounds with potential non-linear optical properties, which could be used in optoelectronic and photonic devices (Nalwa & Miyata, 1997), we herewith report the
of the title compound, (I), (Fig. 1).The geometric parameters of the cation and anion in (I) are comparable to those in previously reported structures (Krishnakumar et al., 2012; Sivakumar et al., 2012). The benzene ring and pyridinium ring makes a dihedral angle of 10.00 (9)°. in the cation.
In the crystal, the anions and cations are linked by weak C—H···O (Table 1 & Fig. 2) and π···π [Cg1···Cg2 (1/2+x,-1/2-y,1/2+z) = 3.7658 (17)Å; Cg1 and Cg2 are the centroids of the N1/C1-C5 and C9-C14 rings, respectively] interactions.

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. |

In continuation of our studies of molecular compounds with potential non-linear optical properties, which could be used in optoelectronic and photonic devices (Nalwa & Miyata, 1997), we herewith report the crystal structure of the title compound, (I), (Fig. 1).
The geometric parameters of the cation and anion in (I) are comparable to those in previously reported structures (Krishnakumar et al., 2012; Sivakumar et al., 2012). The benzene ring and pyridinium ring makes a dihedral angle of 10.00 (9)°. in the cation.
In the crystal, the anions and cations are linked by weak C—H···O (Table 1 & Fig. 2) and π···π [Cg1···Cg2 (1/2+x,-1/2-y,1/2+z) = 3.7658 (17)Å; Cg1 and Cg2 are the centroids of the N1/C1-C5 and C9-C14 rings, respectively] interactions.
