The advantages to be gained in the study of coordination compounds by concurrently carrying out electrostatic-covalent model analyses and experimental measurements is illustrated. Even though coordination compounds are not soluble in solvation minimized solvents, the analyses can indicate when solvation contributions are dominating trends in reactivity. They can also suggest additional experiments to aid in the understanding of the reaction chemistry and spectroscopy. The electrostatic-covalent analyses of various physicochemical measurements on coordination compounds provide a quantitative interpretation of the acceptor properties and a quantitative model for invoking steric, π-bonding and solvation effects. Compared to reported analyses with other scales, the electrostatic-covalent fit does not simply provide a better data fit, but often provides a different interpretation of the meaning of the experiment. It is shown that in studies where the varied ligands are limited to a single family of donors (e.g. substituted pyridines), a wide variation in the types of substituents on the family of donors is needed to define the chemistry.
