2,2'-[2,4-Bis(naphthalen-1-yl)cyclobutane-1,3-diyl]bis(1-methylpyridinium) diiodide: thermal-induced [2 + 2] cycloaddition reaction of a heterostilbene

Abstract: The asymmetric unit of the title compound, C₃₆H₃₂N₂²⁺·2I^-, consists of one half-molecule of the cation and one I^- anion. The cation is located on an inversion centre. The dihedral angle between the pyridinium ring and the naphthalene ring system in the asymmetric unit is 19.01 (14)°. In the crystal, the cations and the anions are linked by C-HI interactions into a layer parallel to the bc plane. Intra- and intermolecular [pi] - [pi] interactions with centroid-centroid distances of 3.533 (2)-3.807 (2) Å are also observed.
