Such an empirical adjustment was firstly developed for a set of similar MOFs containing mostly Zn, based on the systematic employment of 25% of Hartree-Fock exact exchange in PBE0 functionals. To verify the validity of this approach, we have selected one MOF for each metal node to be evaluated at a higher level of theory (with a hybrid functional, PBE0). The full list of all evaluated metal nodes is highlighted in Table .
