合成了 8-羟基喹啉取代的二氧四胺大环配体 ,此类配体含有两个独立的螯合基团 ,在适当情况下能分别与金属离子配位 .在 ( 2 5.0± 0 .1 )℃ ,I=0 .1 mol.dm- 3　 Na NO3条件下 ,用 p H法测定了配体 :金属离子 =2 :3(物质的摩尔比 )二元配合物的稳定常数 ,并依据滴定数据讨论了物种的可能构型 8-hydroxyquinoline substituted diaminetetraamine macrocyclic ligands have been synthesized. These ligands contain two independent chelating groups, which can coordinate with metal ions respectively when appropriate. In (2 5.0 ± 0 .1) ℃, I = 0. 1 mol.dm-3 Na NO3, the stability constants of binary complexes of ligand: metal ion = 2: 3 (molar ratio of substance) The possible conformations of species are discussed on the basis of titration data
