摘　　要：用室温固相法分别合成了以二乙三胺、三乙四胺为配体、以钴为中心离子的配合物。室温下,每摩尔配合物消耗2molO2,其中1molO2用来和钴离子配位形成超氧配合物,另外消耗的1molO2则是由于配体被活化氧氧化所致。采用混合溶济法分离出两种固态氧合配合物犤Co(NH2CH2CH2N=CHCH2NH2)2O2犦(Ac)2·2H2O和犤Co(NH2CH2CH2N=CHCH2NHCH2CH2NH2)2O2犦(Ac)2·2H2O。通过元素分析、红外光谱、电导、XRD、NMR、热分析等测试手段研究了该配合物的性质,确定了该配合物的组成,初步探讨了相关机理。Two cobalt complexes with diethylenetriamine(dien) and triethylenetetramine(trien) as ligands were synthesized by solid-state reaction at room temperature. It was found that one mole of complex reacted with two moles of oxygen at room temperature. One mole O-2 coordinated to Co complex and formed superoxo type oxygenated complex. The reason of excess oxygen uptake is that the ligand was oxidatively dehydrogenated ( - CH2 - NH - --> -C = N-). That is, molecular oxygen could be activated by the coordination with cobalt complex. Two oxygenated complexes prepared via solid-state reaction were isolated and characterized by elemental analysis, IR, XRD, TG/DTA, NMR and molar conductance.
