Synthesis and characterization of a dinuclear ferric complex with redox-active ligands

► In this manuscript we show the syntheses of a dinuclear ferric complex with an interesting non-innocent ligand system. ► The crystal structure of the ferric complex exhibit nano-sized channels. ► The spectroscopic, magnetic and electrochemical properties are studied in comparison to related complexes. ► This comparison provides new insights into the electrochemical properties of ferric complexes with phenolate ligands. ► Evidences for high-valent iron complexes are shown.
