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