In the title compound, C(12)H(11)N(2) (+)·I(-), the aromatic rings are oriented at a dihedral angle of 73.40 (3)°. In the crystal structure, π-π contacts between the pyridine rings and the benzene and pyridine rings [centroid-centroid distances = 3.548 (3) and 4.211 (3) Å] may stabilize the structure.
