Synthesis and characterization of two novel high valent dinuclear complexes with a triphenolate ligand bearing functional groups

• Two novel high valent complexes [M-2(III, III)L(mu-OAc)(2)](PF6)-P-. (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 [Mn-2(II, II)(bpmp) (mu-OAc)(2)](CIO4)-C-. (10). These improvements decreased the difference between the new model and (Mn)(4) cluster (OEC in nature).
