摘要
由冠醚化双schif碱L1H2L4H2与醋酸钴(Ⅱ)或硝酸钠(Ⅰ)/醋酸钴(Ⅱ)反应,分别制得了它们的钴(Ⅱ)配合物1~4和钠(Ⅰ)/钴(Ⅱ)双核配合物5.测定了1~5的氧合常数Ko2,并与非冠醚化品种进行比较,讨论了冠醚环及其配合的钠离子对氧分子加合性能的影响.
Crowned binary Schiff base L 1H 2 L 4H 2 reacted with Co(OAc) 2 or NaNO 3/Co(OAc) 2 to obtain their cobalt(Ⅱ) complexes 1~4 and sodium (Ⅰ)/cobalt(Ⅱ) binuclear complex 5.The adduction constants for dioxygen of these complexes 1~5 were measured and the influences of crown ether ring and Na + coordinated in ether ring on dioxygen affinity were discussed.The results showed that crowned Schiff base cobalt(Ⅱ) complexes was superior to uncrowned analogues 4~9 in the dioxygen affinities of the complexes.
