Synthesis, structure and catalase-like activity of a new dinuclear mixed valence MnIIMnIII complex containing an unsymmetric N5O2 donor ligand

The new dinuclear mixed valence [MnIIMnIII(BPBPMP)(OAc)2]BF4 complex with the unsymmetrical polydentate ligand 2-bis[{(2-pyridylmethyl)-aminomethyl}-6-{(2-hydroxybenzyl)(2-pyridylmethyl)}-aminomethyl]-4-methylphenol (H2BPBPMP) was synthesized. The complex has an MnIIMnIII(μ-phenoxo)(μ-OAc)2 core and was structurally, IR and UV–Vis spectroscopically and by cyclic voltammetry characterized. The reactivity towards H2O2 shows a catalase-like activity.
