a

dcm is the distance between the center of the ring and the near Mg atom on the surface. .../TZP//.../DZP indicates a single-point calculation of the optimized geometry at the DZP level, whereas CP indicates a counterpoise-corrected basis set. Elapsed time per SCF cycle (E.T.scf), only for the adsorbate on the surface, is reported for the corresponding theoretical level.

b

This work.

c

As a without CP correction.

d

Elapsed time per SCF cycle without D4 correction.

e

Elapsed time at PBE/PW (VASP).
