Abstract

To identify the short-lived, highly-active iron intermediate generated in situ for water oxidation, we describe here a new complex 1 by subtle modulation of the TPA ligand and succeed in capturing the high-valent Fe^IV(O) species, which is responsible for the O–O bond formation and oxygen evolution with higher efficiency.
