Abstract
It was shown on the example of two-point interaction of hydrosulfate and dihydrophosphate with hexaazamacrocyclic complexes of nickel(II) that the presence of nitrogen atoms in the ligand molecule of conformationally rigid chelate rings with an equatorial unshared pair of electrons leads to a decrease in the anionbonding efficiency; however, it enhances the differentiating effect between them in comparison with the receptor in which the nitrogen atom is included in a conformationally flexible chelate ring.
