摘要
Reactions of quinquedentate Schiff base ligands with Mn and Cu ions afforded icosa- and hexadecanuclear mixed-metal clusters in which dinuclear Cu-II complexes trapped oxo-bridged [(Mn8Mn4O12)-Mn-III-O-IV] and [(Mn6O6)-O-III] cores, respectively. Maximum entropy method analysis for synchrotron X-ray diffraction data was used to determine the oxidation states of the Mn ions.
