Relatively slow water exchange in a pentaco-ordinate macrocyclic cobalt(II) complex
Abstract
The rate of water exchange in the pentaco-ordinate CoII complex of 1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclotetradecane has been determined to be 4·2 × 104 s–1 at 25 °C with ΔH*= 36·5 ± 1·4 kJ mol–1 and ΔS*=–34 ± 4 J mol–1 K–1.
