Three redox series of complexes of the general formula RuII bpy 2LL an RuII Py4LL bpy2,2-bipyridine are reported, where LL are the ligands, 1,2-dihydroxybenzen, 2-aminophenol or 1,2-diaminobenzene. These ligands can exist in the fully reduced catechol form, or the one and two electron oxidized semiquinone and quinone forms. Electronic and electron spin resonance spectroscopic, and electrochemical data are discussed in terms of orbital mixing and electronic structure, and the number of oxygen or nitrogen atoms in the coordinating ligand.
