Synthesis, characterization, and reactivity of a side-on manganese(iii)–peroxo complex bearing a pentadentate aminopyridine ligand

Abstract

A manganese(II) complex has been prepared with a proline-derived pentadentate ligand (Pro3Py), and it can be converted to a peroxomanganese(III) complex in the presence of H₂O₂ and triethylamine. The resulting peroxomanganese(III) complex was well characterised by UV-vis, EPR and ESI-MS techniques, and the geometric structure was discussed based on DFT calculations.
