Water Exchange
The exchange between bulk and coordinated water is of fundamental interest as a measure of the intrinsic kinetic lability of metal ions. This rate is relevant to toxicity, catalysis, magnetic resonance imaging, and other effects. For octahedral mono- and dicationic aquo complexes, these exchange processes occur via an interchange pathway that has more or less dissociative character. Rates vary by a factor of 1018, 3+ being the slowest and + being one of the fastest for octahedral complexes. Charge has a significant influence on these rates but non-electrostatic effects are also important.
