摘要：

The volumes of activation in cm3 mol−1 for the aquation of Co(CN)5X3− were determined at 40°C and μ = 1 M (NaClO4) to be + 7.8 ± 0.5 for X = Cl−, + 7.6 ± 0.6 for X = Br−, + 14.0 ± 0.7 for X = I−, and + 16.8 ± 0.5 for X = N3− (0.1 M HClO4), respectively. The volumes of activation for the aquation of Co(CN)5Cl3− at μ = 0.1 M are + 10.0 ± 0.6 cm3 mol−1 and ± 9.1 ± 0.3 cm3 mol−1 at 40°C and 25°C, respectively. The corresponding values for the anation of Co(CN)5OH22− (at 40°C) and μ = 1 M by Br−, I−, and NCS− are +8.4 ± 1.0, +9.4 ± 1.6, and +8.2 ± 0.9 cm3 mol−1, respectively. These data are discussed in terms of a dissociative (D) mechanism. Copyright © 1979 Verlag GmbH & Co. KGaA, Weinheim
