Abstract: In the title compound, 2C₁₄H₁₄NO⁺·I₃^-·I^-, the cations are almost planar and exist in E configurations. The dihedral angles between the pyridinium and benzene rings in the two unique cations are 2.6 (2) and 2.8 (2)°. O-HI hydrogen bonds and weak C-HI interactions are observed in the crystal structure. The cations are arranged in a zigzag fashion along the c axis and are packed in an antiparallel manner into sheets parallel to the bc plane. These sheets are interconnected via O-HI hydrogen bonds and weak C-HI interactions to form a three-dimensional network.
