We have recently reported a series of iron polypyridyl monophenolate compounds that are active for catalytic proton reduction. Sulfur analogues of these complexes were also synthesized and exhibited higher activity than the monophenolate catalysts. Unfortunately, these sulfur complexes exhibited poor stability when compared with the iron polypyridyl monophenolate complexes. Herein we report the development, synthesis, and characterization of a tetradentate dithiolate ligand that shows high activity for proton reduction when complexed with iron and cobalt. Cyclic Voltammetry and bulk electrolysis are used to compare the relative activity and stability of these catalysts.
