✦ Synopsis

The reactions of e aq Ϫ , CH 2 OH⅐, (CH 3 ) 2 COH⅐, O H ⅐ and N 3 ⅐ radicals with peroxo ؒϪ CO , 2 terpyridine complexes of Cu(II), Zn(II), and Cu(II)-Zn(II) in aqueous solution were investigated by pulse radiolysis. The primary products from the reduction and oxidation of the macrocyclic complexes were assigned a radical nature by comparing their optical spectra with those of Cu(I), Zn(I), and Cu(III) species. Such metal-ligand radical products undergo disproportionation that does not lead to the formation of Cu(0) or colloidal copper.
