The preparation of some phenylazo substituted tetra-aza macrocycle complexes is reported. The electrochemical properties of these compounds have been examined using polarographic and voltammetric techniques. These studies revealed that both the ligand and metal are electrochemically active. The reduction of the azo function has been shown to occur through a single four-electron process. When a nitro group was also present the nitro function was reduced in a six-electron wave, cathodic of the azo moiety.
