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2 mol O2,其中1 mol O2用来和钴离子配位形成超氧配合物,另外消耗的1 mol O2则是由于配体被活化氧氧化所致.采用混合溶剂法分离出两种固态氧合配合物[Co(NH2CH2CH2N=CHCH2NH2)2O2](Ac)2•2H2O和[Co(NH2CH2CH2N=CHCH2NHCH2CH2NH2)2O2](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.

Abstract: 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 O2 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.
