Abstract	Herein, we report the manganese complex with a novel trianionic ligand , the pentafluorophenyldipyrrinphenol ligand $DPPH_{3}.$ The X-ray crystal structure reveals that the $Mn^{III}$ complex exists in a dimeric form in the solid state. Electrochemical studies indicate two quasi-reversible one electron oxidation processes. EPR data on the one electron oxidised species in solution support the formation of a monuclear Mn complex with an S = 3/2 spin system. Preliminary studies towards epoxidation reactions were tested in the presence of iodosylbenzene (PhIO) and are in favour of an oxygen-atom-transfer (OAT) reaction catalyzed by the $Mn^{III}$ complex.
