Iron(III) complexes of the tris-(3-aminopropyl) derivative of a 14-membered tetraazamacrocycle: Potentiometric, spectroscopic and electrochemical studies

The potentiometric, UV-Vis, EPR and IR spectroscopic and electrochemical properties of mono- and dinuclear iron(III) complexes of 3,7,11-tris-(3-aminopropyl)-3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15-triene, L1, were investigated in aqueous solution.
