摘要：

A dinuclear manganese(II) complex [Mn2(L)(PhCO2)2(NCS)] [L = 2,6-bis{ N-[2-(dimethylamino)ethyl]iminomethyl}-4-methylphenolate(1-)] decomposes H2O2 catalytically in dimethylformamide solution; two oxomanganese(IV) species {Mn(IV)(=O)}2 and Mn(II)[Mn(IV)(=O) are detected for the first time as intermediates in the H2O2 disproportionation reaction based on mass spectrometric and visible spectral studies.
