Artykuł
The structure of two ortho-hydroxy N-methyl Schiff bases as well as the selfcondensation product of 2-(N-methyliminomethyl)-phenol are determined by X-Ray crystallography and by ab initio DFT, on B3LYP/6-31G** level, calculations. Electronic coupling between acidic and basic centres of the molecules, especially effective in the proton transfer structure, is discussed on the basis of detailed analysis of differentiation of bond lengths both in aromatic and chelate rings. Consequences of this coupling on the intramolecular hydrogen bonding and proton transfer process are discussed.
