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

ABSTRACT: In the title compound, C(12)H(12)NS(+)·C(6)H(4)ClO(3)S(-), the cation is almost planar and exists in the E configuration. The cations and anions form alternate layers parallel to the ab plane. Within each layer, both cations and anions form chains directed along the b axis. The mol-ecules are inter-connected by weak C-H?O inter-actions into a three-dimensional network. The crystal structure is further stabilized by C-H?? inter-actions involving the thio-phene ring. The sulfonate and thio-phene groups are involved in weak intra-molecular C-H?O and C-H?S inter-actions, respectively. The latter intra-molecular hydrogen bonds produce S(5) ring motifs.
