(Received 18 January 2013; accepted 8 February 2013; online 6 March 2013)

The asymmetric unit of the title salt [systematic name: 1-benzhydryl-4-cinnamylpiperazine-1,4-diium bis(p-toluenesulfonate) dihydrate], C₂₆H₃₀N₂²⁺·2C₇H₇O₃S⁻·2H₂O, consists of a diprotonated cinnarizinium cation hydrogen bonded through two water molecules to two independent p-toluenesulfonate anions, one which is disordered over two sets of sites in a 0.793 (3):0.207 (3) ratio. In the cation, the piperazine ring adopts a chair configuration and contains two positively charged N atoms with quarternery character. The dihedral angle between the two benzene rings in the benzhydryl group is 71.8 (1)°. The benzene ring flanked opposite the piperazine ring is twisted by 75.9 (9) and 8.8 (3)° from these two benzene rings. In the crystal, the [N—H⋯O_water—H⋯O( S)]₂ hydrogen-bonded asymmetric unit is connected by further O—H⋯O hydrogen bonds linking the components into chains along [100].

Cinnarizine (Iupac name: 1-benzhydryl-4-cinnamyl-piperazine) is an antihistamine which is mainly used for the control of nausea and vomiting due to motion sickness. Cinnarizine could be also viewed as a nootropic drug because of its vasorelaxating abilities (due to calcium channel blockage), which happen mostly in the brain and is also used as a labyrinthine sedative (Towse, 1980). A clinical evaluation of cinnarizine in various allergic disorders is published (Barrett & Zolov, 1960). Cinnarizine can be used in scuba divers without an increased risk of central nervous system oxygen toxicity. The crystal structures of some related compounds viz., cinnarizine (Mouillé et al., 1975), cyclizine hydrochloride (Bertolasi et al., 1980), cinnarizinium dipicrate (Jasinski et al., 2011), cinnarizinium 3,5-dinitrosalicylate (Dayananda et al., 2012), cinnarizinium picrate (Song et al., 2012), have been reported. In view of the importance of cinnarizine, this paper reports the crystal structure of the title compound, C₂₆H₃₀N₂₊ . C₁₄H₁₄O₆S₂^- . 2H₂O, (I).

The asymmetric unit of the title salt (Fig .1), C₂₆H₃₀N₂₊ . C₁₄H₁₄O₆S₂^- . 2H₂O consists of a diprotonated cinnarizinium cation hydrogen bonded through two water molecules to two independent p-toluenesulfonate anions, one of which is disordered in a 0.793 (3):0.207 (3) ratio. In the cation, the piperazine ring, N1/C1/C2/N2/C3/C4, adopts a chair configuration with puckering parameters Q = 0.585 (2)Å, θ = 180.0 (19)°, ϕ = 150 (10)° (Cremer & Pople, 1975) and contains two positively charged N atoms with quarternery character. The dihedral angle between the two benzene rings in the benzhydryl group is 71.8 (1)°. The benzene ring flanked opposite the piperazine ring is twisted by 75.9 (9)° and 8.8 (3)° from these two benzene rings. The bond lengths in the title compound are as expected (Allen, et al., 1987).

In the crystal, N—H···O hydrogen bonds (Table 1) from the diprotonated N atoms of the cation to nearby water molecules which subsequentially form O—H···O hydrogen bonds to the two p-toluenesulfonate anions link the components into infinite 1-D chains along [100] (Fig. 2).

Experimental top

Cinnarizine (3.68 g, 0.01 mol) and p-toluenesuphonic acid monohydrate (1.90 g, 0.01 mol) were dissolved in hot dimethyl sulphoxide solution and stirred over a heating magnetic stirrer for few minutes. The resulting solution was allowed to cool slowly at room temperature. X-ray quality crystals of the title compound appeared after a few days. (M.P.: 373–378 K).

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 > 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.
