✦ Synopsis

In the title compound, C 5 H 6 N + ÁC 15 H 11 O 4 S À , the C-C-C-C torsion angle of À166.9 (2) between the 5-vinylbenzenesulfonate group and the phenyl ring indicates the nonplanarity of the system. The NH group of the pyridinium ring has an intermolecular contact with a sulfonyl O atom. Six intermolecular C-HÁ Á ÁO hydrogen bonds are also observed in the crystal structure.
