ESR and spectrophotometric studies have been made of a number of 1 : 1 complexes of copper (II) with ethylenediamine, its analogues, and amino acids in aqueous-methanolic solutions. It has been shown that the complexes in the solutions are characteristic of copper(II) ions with a normal tetragonal environment and that their metal-ligand bondings are intermediate in the degree of covalency between those of hydrated cupric ions and the corresponding 1 : 2 complexes. The disproportionation constants and their temperature dependences, determined for the 1 : 1 complexes by the ESR and spectrophotometric methods, have been discussed, with particular empahsis on the fact that those values are in fair agreement with those derived from the step-by-step formation constants and the thermodynamic data obtained in aqueous solutions in the literature.
