Abstract: | Comparative analysis of the calculated values of the equalized electronegativity, polarity, hardness (softness) of the coordination bond, and the effective charges of the metal atoms in Pb and Cd tetrafluoroborate complexes with nitrogen-containing bases was performed. The above characteristics were shown to depend on the electron-donor properties of the starting organic ligands. It was shown that an increase in the organic base hardness brings about an increase in hardness of the metal–ligand bond in a complex. |
