center in NO2-NiTPP/Cu(100) has a d 8 configuration with two unpaired electrons, which is in contrast to the situation in gas-phase molecules where the central ion is in a d 8 configuration without unpaired [...] unpaired electrons. Thus, NO2 adsorption enables a spin switching from d 9 to d 8 with two unpaired electrons. Interestingly, the electronic structure of the molecular macrocycle is only weakly perturbed by the …
