| 摘 要： | 采用固相反应合成了三个新的席夫碱钴(II)配合物, 在室温下, 将其与O2作用, 1 mol配合物吸收2 mol O2, 得到三种固态氧合配合物[Co•(L1)2•(O2)2](NO3)2•2H2O [L1＝N,N-二(4-羟基-3-甲氧基苯亚甲基)二乙烯三胺], [Co•(L2)2•(O2)2](NO3)2•2H2O [L2＝N,N-二(4-羟基-3-甲氧基苯亚甲基)三乙烯四胺]和[Co•(L3)2•(O2)2](NO3)2•2H2O (L3＝N,N-二(4-羟基-3-甲氧基苯亚甲基)四乙烯五胺]. 通过元素分析、红外光谱、核磁共振氢谱(1H NMR), TG/DTA、摩尔电导率、紫外等测试手段确定了氧合配合物的组成. 采用失重法测定了氧合配合物中的配位氧, 确定1 mol钴配合物吸收2 mol O2, 其中1 mol O2用来和钴离子配位形成超氧配合物.

| Abstract: | Three new cobalt(II) Schiff base complexes were synthesized by solid state reaction at room temperature. It was found that each Co complex could react with two equiv. of oxygen at room temperature. And the oxygenated complexes [Co•(L1)2•(O2)2](NO3)2•2H2O (L1＝N,N-bis(4-hydroxy-3-methoxybenzyl)- diethylenetriamine), [Co•(L2)2•(O2)2](NO3)2•2H2O (L2＝N,N-bis(4-hydroxy-3-methoxybenzyl)triethylene-tetramine) and [Co•(L3)2•(O2)2](NO3)2•2H2O (L3＝N,N-bis(4-hydroxy-3-methoxybenzyl)tetraethylene- pentamine) were obtained and characterized by elemental analysis, IR spectra, 1H NMR, TG/DTA, molar conductance and UV-Vis measurement. The coordinated oxygen contents in the oxygenated complex were also determined by mass loss method. It was found that one O2 molecule coordinated to the Co ion and formed superoxo type oxygenated complex. |
