title: 2-[(N-Benzyl-4-methyl-benzene-sul-fon-amido)meth-yl]pyridinium nitrate.
abstract: In the title compound, C(20)H(21)N(2)O(2)S(+)·NO(3) (-), the dihedral angle between the pyridinium and phenyl rings is 81.77 (19)°, that between the pyridinium and tolyl rings is 1.36 (18)°, and that between the phenyl and tolyl rings is 82.69 (19)°. In the crystal, the components are linked by strong charge-assisted bifurcated N(+)-H⋯(O,O) hydrogen bonds and the packing is consolidated by numerous weak C-H⋯O bonds and π-π stacking inter-actions [for the latter, centroid-centroid separation = 3.868 (2) Å].
