Asymmetric mixed valence manganese complexes containing the [MnIII(µ-O)2(µ-MeCo2)MnIV]2+ core and their catalase reactivity
Abstract
Two asymmetrically ligated, dinuclear, mixed valence complexes [MnIVL (µ-O)2(µ-MeCO2)MnIII(MeCO2)2]1 and [MnIVL(µ-O)2(µ-MeCo2)MnIII(bpy)(MeOH)](ClO4)2·MeOH 2b have been synthesized (L = 1,4,7-trimethyl-1,4,7-triazacylononane, bpy = 2,2′-bipyridyl) and their structures have been determined by X-ray crystallography; 1 and 2b catalyse the disproportionation of aqueous H2O2.
