Abstract

Abstract The mobility of coordinated methanol in the complex [Co(II)(Benzo[15]crown-5)(CH3OH)2]f + was studied in nitromethane. The methanol exchange mechanism tends to an associative nature with an increasing amount of methanol in the solutions as can be deduced from the activation entropy. All activation data can be combined in an isokinetic relationship which is also valid for the respective complex with the unsubstituted [15]crown-5 ether ligand
