The stability of Cu(II)-α -aminoacids-13-(2'-hydroxy-3', 5'-substituted benzyl)-1, 4, 8, 11-tetraazacyclotetradecane-12, 14-dione (RTADO-14) ternary complex compounds has been studied by means of pH titration method at 25.0±0.1℃ and I=0.1 mol.dm^-^3 KNO3. The formation constants of ternary complex compounds were obtained. The structures of ternary complex compounds and the effect of substituents on macrocyclic ligands were also discussed.

Key words: AMINO ACID, STABILITY, COPPER COMPLEX, FREE ENERGY
