用pH电位滴定法在 (2 5 .0± 0 .1)℃、I =0 .1mol·dm-3 KNO3 条件下测定了钴 (Ⅱ )、锌 (Ⅱ )离子与 6 (2′ 羟基 3′ ,5′ 取代苄基 ) 1,4,8,11 四氮杂环十四烷 5 ,7 二酮形成二元配合物的稳定性以及钴 (Ⅱ ) 5 取代邻菲罗啉与 6 (2′ 羟基 3′ ,5′ 取代苄基 ) 1,4,8,11 四氮杂环十四烷 5 ,7 二酮形成三元配合物的稳定性 ,并探讨了二氧四胺大环配体与 5

The stability of cobalt(Ⅱ)-6-(2′-hydroxy-3′,5′-substitutedbenzyl)-1,4,8,11-tetraazacyclo-tetradecane-5,7-dione binary complex and of Zinc(Ⅱ)-dioxotetraamines macrocycles binary complex and of cobalt(Ⅱ)-5-substituted-phenanthrolines-dioxotetraamines macrocycles ternary complex compounds was studied by means of pH titration method at (25.0±0.1)℃ and I=0.1mol·dm -3KNO 3. The formation constants of binary and ternary complexes were obtained. The effects of substituents on macrocyclic ligands and on 5-substituted-phenanthrolines were also discussed
