Free-energy relationships in coordination chemistry. I. Linear relationships among equilibrium constants

After a review of previous semi-empirical free-energy relationships applying to the formation of metal complexes, the following equations are derived within a framework of logical assumptions[Formula: see text]These compare stability constants of complexes formed by a metal ion M and a ligand L with those formed by a reference metal M s and a reference ligand L o . The derivation of these equations reveals an inherent relationship between the …
