“…55 A systematic series of quinolinium (1 ethylquinolinium, 1 ethyl 2,4 dimethylquinolinium, and 1,2,4 trimethyl quinolinium) triiodides has been examined. 37, 56 These de rivatives differ in both melting points and the ability of retaining molecular iodine. Their molecular structures have been examined by X ray diffraction.…”

“…The cationic and anionic layers in the crystal of low melting (m.p. 56 Iodine molecules usually tend to unite into anionic polyiodine iodide chains [I x ] -when a counterion is planar and can form a stacked structure with channels suited to the polyiodide chain in size and geometry. For instance, in tetrathiafulvalene polytriiodide, stacked cations with an interplanar spacing of 3.32 Å accommodate in their channels linear chains of interconnected symmetric ions I 3 -with an interionic distance of 3.00-3.64 Å.…”

The present review summarizes the results of structural studies of organoiodine complexes. Particular emphasis is given to the role of intermolecular interactions such as halogenhalogen (I...I), hydrophobic, π-π stacking, and hydrogen bonds (C-H...I) in the formation of supramolecular iodine containing architectures. The molecular formula, size, shape, and stability of the polyhalide ion and the way of its coordination by an outer sphere cation or an organic macromolecule depend on the nature and symmetry of the cationic environment, the ability of a solvating solvent to form complexes with iodine, and the conditions of the synthesis. Efforts have been made to highlight a structural and functional variety of iodine containing complexes and estimate the prospects of using them as organic conductors, magnetic materials, liquid electrolytes, and biologically active compounds.

“…N-substituted quinolines are widely employed as materials with second-order nonlinear optical behavior; the properties of such materials directly depend on the composition and spatial arrangement of their molecules [10]. A systematic series of quinolinium (1-ethylquinolinium, 1-ethyl-2,4-dimethylquinolinium, and 1,2,4-trimethylquinolinium) triiodides has been examined [11,12]. The cationic and anionic layers in the crystal of lowmelting (m.p.…”
