1-Methyl-2-[(E)-2-(2-thien-yl)ethen-yl]quinolinium 4-bromo-benzene-sulfonate.

ABSTRACT: In the title compound, C(16)H(14)NS(+)·C(6)H(4)BrO(3)S(-), the cation exists in an E configuration and is essentially planar, the dihedral angle between the quinolinium and thio-phene rings being 3.45 (9)°. The anion is inclined to the cation with dihedral angles of 75.43 (8) and 72.03 (11)°, respectively between the benzene ring and the quinolinium and thio-phene rings. In the crystal, the cations and anions are arranged individually into separate chains along the c axis. The cation chains are stacked in an anti-parallel manner along the a axis by π⋯π inter-actions with centroid-centroid distances of 3.7257 (13) and 3.7262 (14) Å. Weak C-H⋯O and C-H⋯π inter-actions link the cations and anions into a three-dimensional network. Short Br⋯S [3.7224 (5) Å] and Br⋯O [3.4267 (16) Å] contacts are
