Abstract
The kinetics of base hydrolysis of the two title cations, cis-[RhCl2(cyclen)]+(cyclen = 1,4.7,10-tetra-azacyclo-dodecane) and cis-[RhCl2(cyclam)]+(cyclam = 1,4,8,11-tetra-azacyclotetradecane), have been studied over a range of temperature at I= 0.1 mol dm–3(KCl or K[NO3]). The activation parameters have been obtained and possible mechanisms considered. The base-hydrolysis rate of cis-[RhCl2(cyclen)]+, kOH= 37 dm3 mol–1 s–1 at 25 °C and I= 0.1 mol dm–3, is the highest yet reported for halogenorhodium(III) complexes of the [RhCl2(N4)]+ type.Keywords
