A mixture of 2,3-dimethylbenzothiazolium iodide (1 mmol), 5-[(2-hydroxyethyl)methylamino]thiophene-2-carbaldehyde (1 mmol) and acetic anhydride (20 ml) was refluxed for 20 min, than poured into a warm solution of potassium iodide (4 mmol) in water (20 ml). The precipitated product was filtered, washed with water and recrystallized from a methanol/water solution. 1H NMR: (400 Hz, DMSO-d6), d(p.p.m.):8.14 (d, 1H), 8.11 (d, 1H), 7.89 (d, 1H), 7.83 (s, 1H), 7.66 (t, 1H), 7.53 (t, 1H), 6.73 (s, 1H), 6.54 (d, 1H), 4.33 (t, 2H), 4.00 (s, 3H), 3.85 (t, 2H), 3.24 (s, 3H), 1.94 (s, 3H).
All hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with O—H = 0.85, C—H = 0.93–0.97 Å, Uiso(H) = 1.5Ueq(C,O) for methyl H and water H atoms, and 1.2Ueq(C) for the others.

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. |

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.
