| Abstract: The stabilities of Cu(Ⅱ)-1,4,8,11-tetraazacyclotetradecane-12,14-dione(TADO-14) binary complex compound and Cu(Ⅱ)-5-substituted penanthrolines (R′phen)/α-aminoacids-TADO-14 ternary complex compounds have 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 binary and ternary complexes were obtained. The structures of binary and ternary complex compounds and the effects of substituents on ligands R′phen were also discussed. |
