ON SOME 2,4,6-TRIPHENYLPYRIDINIUM 2-BENZIMIDAZOLATE INNER SALTS

Molecular and electronic structure of the titled inner salts la-le is discussed on the basis of the PM3, AM1 and CNDO/2 calculations. Compou nds 1a, 1b and 1c were prepared from idazol-2-yl)-2,6-diphenyl-4-(4-X- phenyl)pyridinium perchlorates (2a-2c) by chromatography on alumina on ly in forms of relatively stable clusters with water and solvent molec ules. Mass spectra of the prepared substances are discussed.
