1-Methyl-2-[(E)-2-(2-thien-yl)ethen-yl]quinolinium iodide.

ABSTRACT: In the title compound, C(16)H(14)NS(+)·I(-), the cation has an E configuration about the C=C double bond of the ethyl-ene unit. The dihedral angle between the thio-phene ring and the quinolinium ring system is 11.67 (11)°. A weak C-H⋯S intra-molecular inter-action involving the thio-phene ring generates an S(5) ring motif. In the crystal structure, the iodide ion, located between the cations arranged in an anti-parallel manner, forms weak C-H⋯I inter-actions. The crystal structure is further stabilized by a π-π inter-action between the thio-phene and pyridine rings; the centroid-centroid distance is 3.6818 (13) Å.
