摘要：A novel high valent [Mn2(III/III)L (��-OAc)2]·PF6 complex is prepared, where L is 2,6-bis {[(2-hydroxy-5-tert-butylbenzyl) (pyridyl-2-methylene)-amino]methylene}-4-methylphenol, which contains additional phenolate functional groups and tert-butyl groups as compared to [Mn2(II/II)(bpmp) (��-OAc)2]·ClO4. In this complex, two pseudo-octahedrally coordinated Mn ions are bridged by a phenolate group and two bidentate acetate ligands. The stronger and more coordinate bonds between anionic phenolate groups and Mn ions in higher oxidation state prevent the dissociation of central ions. The additional tert-butyl groups improve the solubility and electronic cloud density of the ligand. These improvements narrow the disparity between the new model and (Mn)4 cluster (oxygen-evolving center in nature). IR, ESI-MS, NMR (gCOSY, gHMBC, gHSQC) and electrochemistry characterized the new ligand or complex.
