The electrochemical behavior and electrogenerated chemiluminescence (ecl) of Ru(bpz)/sub 3//sup 2 +/ (as the PF/sub 6//sup -/ salt) in acetonitrile solutions were investigated. Oxidation to the 3+ form and reduction to the 1+, 0, 1-, and 2- forms occur at potentials about 0.5V more positive than those for the corresponding bipyridine complex. Emission characteristic of Ru(bpz)/sub 3//sup 2 +/* is produced upon the electron-transfer reaction between the 3+ and 1+ species. Weak emission also results from the reaction of the 3+ species with solvent or impurities.
