Isovalent and mixed-valent diruthenium complexes [(acac)2Ru (II) (μ-bpytz)Ru(II)(acac)2] and [(acac) 2Ru(II)(μ-bpytz)Ru(III)(acac) 2](CI04) (acac = acetylacetonate and bpytz = 3,6-bis(3,5-dimethylpyrazolyl)-1,2,4,5-tetrazine): Synthesis, spectroelectrochemical, and EPR investigation

The title compounds involving the structurally characterized bridging ligand bpytz were characterized, showing very strong electrochemical stabilization of the mixed-valent RuIIRuIII state (K c = 1013.9) but no detectable (ε -1 cm-1) intervalence charge-transfer band in the infrared region. In situ reduction of the neutral precursor produces a diruthenium(II) complex of the bpytz radical anion according to EPR spectroscopy, whereas oxidation of the mixed-valent form leads to a diruthenium(III) species.
