摘要：

The new dinuclear mixed valence [(MnMnIII)-Mn-II(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 (MnMnIII)-Mn-II (mu-phenoxo) (mu-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. (C) 2002 Elsevier Science B.V. All rights reserved.
