Reported are the average distances
in Angstrom (Å), average angles
and dihedral angles
in degrees (deg), number (n) of atoms (C, Mg, or M) interacting with each other (e.g., [ nC–nMg
]), and the number of contact points (C.P.), which is the sum of C
atoms interacting with either an Mg or transition metal. The average
values are calculated from the geometrical parameters reported in
the Supporting Information. M is the transition
metal (e.g., Fe or Ni) of the corresponding surface (e.g., Fe for
Fe-[010]-fo). Missing values shows no interaction between the atoms.
