    • 3+ aqua ions is governed mainly by steric and electrostatic interactions. This gives rise to relatively high kinetic lability with considerably high exchange rates between the waters in the first and second hydration spheres; the TTP coordination geometry is thus the mean structure.

    • An upper limit for kr may be estimated, for example, in 2 where kobs(H2O), 15.6 ms-1 and k obs(D2O), 0.645 ms-1, and since kr is the same for the hydrated and deuterated compounds, kr < 0.645 ms-1. This value may be compared to that calculated for Cm 3+aq, 0.769 ms-1
