In the cation of the title hydrated salt, C₁₉H₂₁N₂O₂S₂⁺·I⁻·H₂O, the benzothiazolium ring system is approximately planar [maximum deviation = 0.0251 (15) Å], and it makes a small dihedral angle of 1.16 (18)° with the plane of the thiophene ring. In the crystal, the cations, anions and crystalline water molecules are linked by classical O—H⋯O, O—H⋯I and weak C—H⋯O hydrogn bonds, forming a three-dimensional supramolecular network. π–π stacking is observed between parallel thiazole rings of adjacent cations [centroid–centroid distance = 3.5945 (16) Å].

Keywords: crystal structure; benzothiazolium iodide salt; hydrogen bonding.

Comment top

Interest in organic compounds with non-linear optical (NLO) properties is driven by the prospective of their applications in optical information technologies. The most common design of molecules with large NLO-active comprises strong electron-donors and acceptors connected by a π-conjugated system (Hao et al., 2009; Zhou et al., 2011). Besides, the introduction about the highpolarizability of sulfur atoms in thiophene rings leads to a stabilization of the conjugated chain and to excellent charge transport properties. In the title compound (I) (Fig. 1), the benzothiazolium-CH═CH-thiophene part of the molecule is nearly coplanar (plane of CH═CH makes angles of 0.663 (8)° and 0.847 (1)° with the planes of the benzothiazolium and the thiophene rings), while in related benzothiazolium derivatives (Quist et al. 2009), the corresponding angles are 5.61 (18)° and 1.78 (19)°, respectively.

Special details top

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.
