In the cation of the title compound, C14H13BrN+·C7H7O3S, the dihedral angle between the benzene and pyridine rings is 8.34 (11)°. The Br atom is disordered over two positions with site occupancies of 0.74 (2) and 0.26 (2). The mol­ecular structure is stabilized by a weak intra­molecular C—H⋯O inter­actions. The crystal structure exhibits weak C—H⋯O and ππ [centroid–centroid distance = 3.7466 (17) Å] inter­actions, forming a three dimensional network.

Comment top

In continuation of our studies of molecular compounds with non linear optical properties which are used in optoelectronic and photonic devices (Bosshard et al., 1995; Nalwa & Miyata, 1997), we herewith report the crystal structure of the title compound (I) (Fig. 1).

The asymmetric unit of the title compound consists of C14H13BrN+ cations and C7H7O3S- anios. The geometric parameters of the title compound are agree well with those of reported structures (Krishnakumar et al., 2012; Sivakumar et al., 2012; Okada et al., 1990). In the cation, the bromine atom is disordered over two positions, with the site occupancies of 0.74 (2) and 0.26 (2). The cation is planar [torision angle C4-C7=C8-C9 = 178.1 (3)°] about the double bond between the two rings in the cation. The dihedral angle between the benzene ring and pyridinium ring in the cation is 8.34 (11)°.

The molecular structure is stabilized by weak intramolecular C-H···O interactions. In the crystal structure, adjacent anions and cations are linked by weak C—H···O (Table 1 & Fig.2) and π···π [Cg1···Cg2 (x,-1/2-y,1/2+z) = 3.7466 (17)Å and Cg2···Cg1 (x,1+y,z) distance = 3.7468 (17)Å; Cg1 and Cg2 are the centroids of the rings (C9/C10/C11/N1/C12/C13) and (C1-C6), respectively] interactions.

Experimental top

The title compound was synthesized by the condensation of 4-methyl-N-methyl pyridinium tosylate, which was prepared from 4-picoline (4.65g, 5 mmol) and methyl p-toluenesulfonate (9.31g, 5 mmol), and 4-bromobenzaldehyde (9.24 g, 5 mmol) in the presence of piperidine. The single crystals suitable for X-ray diffraction were grown by slow evaporation method in room temperature.

Refinement top

H atoms were positioned geometrically and refined using a riding model with C-H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic C-H, C-H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for CH3. The components of the anisotropic displacement parameters in the direction of C4 and C7 were restrained to be equal within an effective deviation of 0.001 using DELU command in SHELXL (Sheldrick, 2008). The disorder of the bromine ligand suggests also disorder of the aromatic ring to which it is attached, but no split model for this ring could be found.

Special details top

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.
