| Abstract: | Aggregation of methylpyrazinium iodide and its derivatives in chloroform and dichloromethane solutions was studied by EAS and 1H NMR spectroscopy. The isopentylpyrazinium iodide ion quadruple formation constants in solutions were evaluated. Formal extinction coefficient in the outer-sphere charge transfer band maxima does not depend on the degree of aggregation in the system. A model suggested for the formation of ion quadruples in solutions was discussed in terms of the density functional theory and using the X-ray diffraction data for crystalline methylpyrazinium iodides and its derivatives. |
