1-(Phthalimidomethyl)pyridinium p-toluenesulfonate

Abstract

In the crystal of the title compound, C14H11N2O2+·C7H7O3S−, the cation and anion interact by way of an aromatic π–π interaction [centroid–centroid separation = 3.5783 (2) Å] and a T-stacking (C—H...π) interaction 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.
