Notes:
The interaction between Cu2+ and the terdentate ligands N-picolinoyl-ethylenediamine, glycine-2-pyridylmethylamide, Nα-(2-pyridylmethyl)-glycinamide and Nα-(2-pyridylmethyl)-glycine-ethylamide, respectively, has been studied by spectrophotometry and potentiometry. At high pH values the ionised amide group undergoes complex formation and the resulting chelates have similar structures and stabilities. In slightly acidic solution however, each ligand gives rise to a different species. These facts are explained by assuming that the neutral amide group coordinates through its carbonyl oxygen atom. The stability constant and the absorption spectrum of each complex have been calculated by computer programmes.
