- 中文摘要: Redox reactions of Co(edta)/sup -/ with Ru(NH/sub 3/)/sub 5/L/sup 2+/ (L=3- and 4-aminopyridine (AmPy)) were found to follow an outer-sphere electron transfer mechanism. The specific rate constants are (3.26.plmin.0.03)*10/sup 2/ and (3.07.plmin.0.04 )*10/sup 3//M-S, for L=3- and 4-AmPy, respectively, at .mu.=0.10M LiClO/sub 4/, pH=8.0 (tris) and T=25.degree.C. The rate constants of oxidations for a series of Ru(NH/sub 3/)/sub 5/L/sup 2+/ complexes are higher than those of the corresponding Fe(CN )/sub 5/ L/sup 3-/ complexes by factors of 4 to 15 even after corrections for differences in reduction potentials and in charges of the complexes. Nonadiabaticity in the reactions of Fe(CN)/sub 5/L/sup 3-/ complexes may account for the difference in the relative reactivities.
