(E)-2-[4-(Dimethyl-amino)-styr-yl]-1-methyl-pyridinium triiodide.

ABSTRACT: The asymmetric unit of the title compound, C(16)H(19)N(2) (+)·I(3) (-), contains a (E)-2-[4-(dimethyl-amino)-styr-yl)-1-methyl-pyrid-in-ium 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 ?-? inter-actions 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.
