A Mononuclear Nonheme Iron(IV)-Oxo Complex of a Substituted N4Py Ligand : Effect of Ligand Field on Oxygen Atom Transfer and C-H Bond Cleavage Reactivity
A mononuclear iron(II) complex [FeII(N4PyMe2)(OTf)](OTf)(1), supported by a new pentadentate ligand, bis(6-methylpyridin-2-yl)-N,N-bis((pyridin-2-yl)methyl)methanamine (N4PyMe2), has been isolated and characterized. Introduction of methyl groups in the 6-position of two pyridine rings makes the N4PyMe2 a weaker field ligand compared to the parent N4Py ligand. Complex 1 is high-spin in the solid st
