2,2'-[2,4-Bis(naphthalen-1-yl)cyclo-butane-1,3-di-yl]bis-(1-methyl-pyridinium) diiodide: thermal-induced [2 + 2] cyclo-addition reaction of a heterostilbene.

ABSTRACT: The asymmetric unit of the title compound, C(36)H(32)N(2) (2+)·2I(-), consists of one half-mol-ecule 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-H⋯I inter-actions into a layer parallel to the bc plane. Intra- and inter-molecular π-π inter-actions with centroid-centroid distances of 3.533 (2)-3.807 (2) Å are also observed.
