Utilization of hydrogen bonds to stabilize M-O(H) units: synthesis and properties of monomeric and manganese complexes with terminal ox and

The formation and properties of a new series of mononuclear Fe(III) and Mn(III) complexes with terminal oxo and hydroxo ligands that are derived directly from dioxygen is presented. Theoretically derived molecular orbital energy level diagrams and corresponding plot for orbitals pertaining to the M(III)-O bonds in [Fe(III)H31(O)2- and [Mn(III)H31(O)]2 is illustrated.
