Abstract

The specific rates of reaction of H atoms, Zn+, Cd+, and Ni+ with Ru(NH3)63+ were determined. The mechanism of reduction of hexaammine complexes by hydrogen atoms is discussed. It is suggested that hydrogen atoms might penetrate the ligand sphere and form a seven coordinated transition state. The redox potentials of the Zn+/Zn2+ and Cd+/Cd2+ couples are estimated as being equal to 2.0 ± 0.4 and 1.8 ± 0.4 V, respectively.
