A 14N n.m.r. study of the exchange reaction Fe(CH3CN)62+ ╲ CH3CN in CH3CN solvent is reported. The value for k 1 (25°C) from the rate law R = 6k1[Fe(CH3CN)62+] is (5.5 ± 0.8) × 105 s-1, ΔH‡ = 9.7 ± 0.7 kcal mol-1, ΔS‡ = 0.3 ± 2.2 cal mol-1 K-1, and A/h = 5.0 × 106 Hz. These data are compared with those of related systems.
