“…Ternary metal complexes have been the subjects of extensive studies for coordination chemists, including bioinorganic chemists. − Ligand pairs utilized in these studies include amino acids, ,− ,− ,,,, peptides, ,, pterin, 2‘-deoxyguanidine-5‘-monophosphate, and catechol . In an early stage of study on the ternary complexes, a general and methodological account for the study of mixed-ligand complexes of amino acids and peptides was outlined and the stability constants of ternary complexes of Cu, Ni, Co, Cd, Zn, Pb, and Ca were tabulated .…”

An Attempt to Discriminate between the Hydrophobic and Aromatic π−π Interactions in the Copper(II) Ternary Complexes CuLA with L = 1,10-Phenanthroline or 2,2‘-Bipyridyl and A = para-X-Substituted Phenylalaninates

For the title complexes, the value of formation constant K(CuL+A) is higher than that of K1(CuA2). According to the mechanistic consideration, log K(CuL+A) is calculated for regular Cu(II) complexes with neither special enhancement nor diminution of the stability constant. Then, the difference of log K(CuL+A)(obs)-log K(CuL+)(calc) represents extrastabilization due to the hydrophobic interactions and the aromatic pi-pi interactions. The former has been found to be proportional to the free energy of the transfer of side chains of aminocarboxylates A. The discrimination between the hydrophobic and the aromatic pi-pi interactions has been attempted.
