Abstract

The electrochemical behavior of the unusual cobalt(II) diphenylazodioxide complex salts [Co(az)₄](PF₆)₂ 1 and [Co(bpy)(az)₂](PF₆)₂ 2 has been studied by cyclic voltammetry. Each complex displays two quasireversible redox couples, which are proposed to correspond to a reduction of Co(II) to Co(I), followed by a ligand-based reduction. Irreversible reductions of 1 are observed at more negative potentials, and are proposed to arise from deposition of elemental Co and the decomposition of transiently formed Co(-I) species. Spectroelectrochemical experiments on both 1 and 2, involving electrolytic reduction followed by reoxidation, are consistent with the quasireversibility observed in the CV measurements.
