Remarkable electronic lability is evident from a preliminary study of a dinuclear cobalt complex with a bis(dioxolene) bridging ligand and tetraazamacrocylic ancillary ligands. Structural, magnetic, spectroscopic, and electrochemical data indicate coinciding metal- and ligand-based mixed-valence involving cobalt(II)/cobalt(III) and catecholate/semiquinonate couples. A thermally stimulated spin-crossover or valence-tautomeric transition is also observed above 200 K.
