spectroscopy and electrochemical methods. The complex cation [Fe(HL1)Cl3]+1a possesses a distorted octahedral geometry in which iron is coordinated by the monoprotonated 4N ligand in a tridentate fashion and the remaining three sites of the octahedron are occupied by chloride ions. The DFT optimized octahedral geometries of 1, 5 and 6 contain iron(III) with a high-spin (S = 5/2) ground state. The catecholate
