Influence of Ligand Exchange on the Redox Potentiala

Compound E1/2 (RuIII/RuII) V vs. NHEb
[RuIIICl6]3 − − 1.36c
[RuIIICl5(Hind)]2 − − 0.87c
trans-[RuIIICl4(Hind)2]− − 0.43
mer-[RuIIICl3(Hind)3]0 + 0.10
trans-[RuIIICl2(Hind)4]+ + 0.59
a

Values taken from ref. (318).

b

Redox potentials in V± 0.02, measured at a scan rate of 0.20 V/s in [n-Bu4N][BF4]/dimethylformamide.

c

Adequate detection was hampered by rearrangement of the complexes in dimethylformamide; therefore, the potentials were estimated using Lever’s parametrization approach (213): E1/2 = SM · ∑ELigand + IM (with SM= 1.14; ECl = −0.24 and EHind = 0.26; IM= −0.35).
