(E,E)-1-Methyl-2,6-distyrylpyridinium iodide. | LitMetric

In the title compound, C(22)H(20)N(+)·I(-), the dihedral angles between the central pyridine ring and two outer benzene rings are 15.30 (10) and 11.82 (11)°. There are inter-molecular π-π stacking inter-actions between the nearest phenyl ring over an inversion-related pyridyl ring, the shortest centroid-centroid distance being 3.672 (3) Å. The crystal structure of the compound indicates the 2,6-distyryl substituents have an E configuration.
