1-Methyl-2-[(E)-2-(2-thien­yl)ethen­yl]quinolinium 4-bromo­benzene­sulfonate

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 thio­phene rings being 3.45 (9)°. The anion is inclined to the cation with dihedral angles of 75.43 (8) and 72.03 (11)°, respec...

Sumario: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 thio­phene 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 thio­phene 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 anti­parallel manner along the a axis by π⋯π inter­actions with centroid–centroid distances of 3.7257 (13) and 3.7262 (14) Å. Weak C—H⋯O and C—H⋯π inter­actions 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 also observed.
