N2 - The rates of reduction of some CoIII pentaamine complexes by HINA·, and , HNA·, radicals were measured. It was found that HNA· is more reactive than HINA·. The redox potential for the couple HINA·/HINA+ was calculated, E° = 0.80 ± 0.02 V. In the presence of large excess of NA, a catalytic enhancement in the reduction of CoIII(NH3)5 NA and CoIII(NH3)5 Pyridine by Eu2+ was observed. The difference in the mechanism of reduction of CoIII(NH3)5 X by Eu2+ where X = NA or INA is discussed. The redox potential of the HNA·/HNA+ couple was estimated, 0.80 < E° < 1.1 V.
