Other functionals behave similarly to BLYP+D3(BJ), except for the problematic M06-L (Fig. ), for which CP-corrected convergence errors show a significant spread on both sides of zero and the distributions of CP- corrected and uncorrected values are difficult to distinguish. As such, CP correction may either improve or degrade the results but does so more-or-less at random, indicative of an overall failure of systematic convergence to the CBS limit. For the double-hybrid functionals (Figs. S5), Dunning and Karlsruhe basis sets behave similarly to what is seen for BLYP+D3(BJ) in Figs. and, but Pople basis sets clearly underbind the complexes when CP correction is applied, where results without CP correction are overbound.
