The asymmetric unit of the title compound, C(21)H(17)F(3)N(3)O(3) (+)·C(7)H(7)O(3)S(-)·H(2)O, contains two formula units. In one of the cations, the pyridinium and trifluoro-methyl benzene rings form dihedral angles of 87.42 (8) and 45.92 (8)°, respectively, with the central benzene ring [79.56 (8) and 43.52 (8)° in the other cation]. In the crystal structure, N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the ions and water mol-ecules, forming a three-dimensional network.
