title: 1-(Phthalimidometh-yl)pyridinium p-toluene-sulfonate.
abstract: In the crystal of the title compound, C(14)H(11)N(2)O(2) (+)·C(7)H(7)O(3)S(-), the cation and anion inter-act by way of an aromatic π-π inter-action [centroid-centroid separation = 3.5783 (2) Å] and a T-stacking (C-H⋯π) inter-action between cations. The dihedral angle between the aromatic rings in the cation is 61.73 (8)°. The ionic units are aligned in a zigzag fashion in the b-axis direction.
