The title compds. involving the structurally characterized bridging ligand bpytz were characterized, showing very strong electrochem. stabilization of the mixed-valent RuIIRuIII state (Kc = 1013.9) but no detectable (e \textless 20 M-1 cm-1) intervalence charge-transfer band in the IR region. In situ redn. of the neutral precursor produces a diruthenium(II) complex of the bpytz radical anion according to EPR spectroscopy, whereas oxidn. of the mixed-valent form leads to a diruthenium(III) species. on SciFinder(R)
