Abstract
It is now widely known that polyamine ligands form very stable complexes with transition metal ions. This stability is measured by the formation constants of these complexes and it is made up of two main contributions: enthalpic (ΔH°) and entropic (ΔS°). The entropic contribution to the complex formation is always positive and favourable, the enthalpic contribution is very often negative and favourable as well. Much effort has been made in order to obtain reliable values of the thermodynamic functions ΔH° and ΔS°. In recent years, commercially available accurate solution calorimeters have made it possible to measure and publishe many ΔH° and ΔS° values. In particular we have studied the systems formed by tetraaza-cycloalkanes (macrocycles) and some transition metals.
