Synthesis and Characterization of Two Novel High Valent Dinuclear Complexes with a Triphenolate Ligand Bearing Functional Groups

Two novel high valent complexes M2(III, III)L(p--OAc)2].PF6 (M=Mn, Fe; 9) were prepared, where L was the tri-anion of 2,6-bis{(2-hydroxy-3-(morpholin-4-yl methyl)-5-tertbutyl benzyl)(pyridyl-2-methyl)amino]methyl}-4-methyl phenol which contained additional phenolic, tert-butyl and morpholin-4-yl methyl groups compared to its parent Mn2(Ⅱ, Ⅱ)(bpmp)(μ-OAc)2]-ClO4 (10). These improvements decreased the difference between the new model and (Mn)4 cluster (OEC in nature).
