摘要： 合成了三核锰(Ⅲ)Schiff碱配合物:Mn3O(Salea)2(C2H3O2)3·HC2H3O2(其中Salea2-为水杨醛缩乙醇胺Schiff碱阴离子),经元素分析、磁矩、化合价、电导率、热分析、红外、紫外光谱等进行表征,并利用氧电极进行了放氧活性测试,发现在对苯醌存在下配合物能促使水分解释放氧气,其反应受温度、对苯醌和配合物浓度等因素影响,并提出了可能的放氧反应方程.

Abstract: The trinuclear manganese (Ⅲ).Schiff base complex Mn3O(Salea)2(C2H3O2)3· HC2H3O2(where salea2-is the dianion of ONO tridenate Schiff base prepared by condensing ethanol amine with salicylaldehyde) was synthesized and characterized by magnetic susceptibilities, molar conductivities, infrared spectra, electronic spectra and thermoanalyses, etc. The measurement of oxygen evolving activity was performed using an oxygen electrode. In the aqueous solution involving p-benzoquinone, the complex can promote water to decompose and liberate dioxygen and this is affected by temperatures and concentrations of p-benzoquinone and the complexs. Apossible equation for oxygen evolving reaction is suggested.
