| 摘 要： | Heterometallic copper(Ⅱ)-lanthanide(Ⅲ) complexes have been made with a variety of exclusively O-donor ligands including betaines (zwitterionic carboxylates) and chloroac-etate,which are dinuclear CuLn,tetranuclear Cu2Ln2,pen-tanuclear Cu2Ln2,and octadecanuclear Cu12Ln6 complexes.Hie results show that subtle changes in both the carboxylates and acidity of the reaction solution can cause drastic changes in the structures of the products.Magnetic studies exhibit that shielding of the Ln3 4f electrons by the outer shell electrons is very effective to preclude significant coupling interaction between the Ln3 4f electrons and Cu2 3d electrons in either a mono-atomic hydroxide-bridged,or a carboxylate-bridged system.
