Sumario:The asymmetric unit of the title compound, C(16)H(19)N(2) (+)·I(3) (−), contains a (E)-2-[4-(dimethyl­amino)­styr­yl)-1-methyl­pyrid­in­ium cation and half each of two triiodide anions. The complete triiodide anions are each generated by inversion symmetry. The planar cation has all of its eighteen non-H atoms situated on a mirror plane. In the crystal, the cations are stacked along the b axis by π–π inter­actions with a centroid–centroid distance of 3.5757 (13) Å. The triiodide anions are located between the cations. The crystal structure is further consolidated by short C⋯C [3.322 (9)–3.3952 (19) Å] contacts.
