The solvent dependence of metallophthalocyanine redox equilibria is reported for manganese, iron and cobalt phthalocyanines in dimethylacetamide, dimethylsulfoxide and in pyridine. Considerable sensitivity is observed with iron and cobalt, much less with manganese. Both positive and negative deviations of redox potentials with solvent donicity as defined by the Gutmann solvent donicity scale are observed and explained, in terms of coordination number, spin state and the nature of the metal ligand bond. Comparison is made with analogous porphyrin derivatives. Author
