Synthesis, Characterization and Oxygen Evolving Activity Determination for Mn3O(Salea)2(C2H3O2)3·HC2H3O2

Abstract

Abstract: The trinuclear manganese (Ⅲ).Schiff base complex Mn₃O(Salea)₂(C₂H₃O₂)₃· HC₂H₃O₂(where salea^2-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.

Key words: Manganese(Ⅲ), Schiff base, Trinuclear complex, Oxygen evolving activity
