The combination of the (5s5p4d)/[4s4p3d] + 2s1p1d basis set for lanthanoids and the cc-pvdz basis set for non-lanthanoids can be suggested as optimal for further studies of lanthanoid cation complexation as it is a good compromise between cost and accuracy.

In the current study, we performed calculations for 15 eight- and nine-coordinated lanthanoids by using nine computational chemistry methods.
The synergistic extraction of trivalent actinoids and lanthanoids is of great interest because of the high extraction efficiency of these metal ions in the presence of a chelating agent and a neutral donor [1-7].

The separation of the lanthanoids using HTTA-PAR and HP-PAR mixtures can be assessed by the separation factors calculated as a ratio of the distribution coefficients of two adjacent lanthanoids (the heavier and the lighter one).
