title: Pyridinium 4-(trifluoro-meth-yl)benzene-sulfonate.
abstract: The title salt, C(5)H(6)N(+)·C(7)H(4)F(3)O(3)S(-), is an ion pair in which the pyridium cation is linked to the 4-(trifluoro-meth-yl)benzene-sulfonate anion by an N-H⋯O hydrogen bond. The F atoms of the trifluoro-methyl group are disordered over two sites in a 0.584 (9):0.416 (9) ratio.
