Stability, coordination saturation and extraction behaviour of neutral complexes of metals in the framework of the theory of strong and soft acids and Pirson's bases

In modern practice there is a big volume of experimental data on behaviour of metals (rare earths, actinides) in two-phase systems and interpretation of these date is based on assumption that chemical shift of binding energy of inner electrons is changed as a result of effective charge change. Analysis of experimental data results in interesting in the framework of this paper conclusions: binding energy of inner electrons is changed in dependence on electronegativity of ligands. In turn the change of effective charge leads to change of energy of atomic orbitals and/or molecular orbitals of a complex. In context of this paper it is important to point out that these changes are specific for each complexes
