    • 3+. One also notes that the van Veggel et al. parameters satisfactorily reproduce free energies for hydration of lanthanides and cation-water distances, but seem to overestimate the CN's (from 10 to 9 across the lanthanide series). Our parameters are therefore satisfactory from the energy and structural points of view for aqua ions.

    • note
    • Changes in solvent-solvent interaction energies also contribute to the perferred stabilities. However, the latter can hardly be compared, as the number of solvent molecules is not identical for the two simulated systems, and their energies display large statistical fluctuations. In addition, entropy effects, not amenable to simple evaluation from the MD trajectories, also contribute to the nature of the complex.
