    The studies reported in this work were undertaken to explain the correlation between the Mossbauer chemical shifts and charge localised on the central atoms. The complexes of the Sn, Sb, Al and I with organic ligands seem very interesting model compounds for the studies of the donor-acceptor interactions. In complexes with organic ligands, a proportional relation was found between the populations of the 5s- and 5p-orbitals in Sb and Sn atoms, whereas in complexes with inorganic ligands such a relation was not observed. Interpretation of this difference is closely connected with a multiple parameter character of the chemical shift dependence on the central atom charge. A strong correlation was established between the differences in the energies in the inner energy levels of tin, antimony, chlorine atoms and the corresponding ClK(α) shifts. The correlation dependencies obtained can be used to characterise the donor ability of ligands.
