Adsorption models of [MnIII6CrIII]3+ on HOPG. The first layer of the SMM is stabilized by mirror charges having their origin in the metallic HOPG substrate.(a) Model #1: Alternating stacking of SMM and anions. (b) Model #2: anions are in between the layer. (c) Model #3: similar to model #2 but the first layer is free of anions due to the mirror charge of the substrate thus leading to different heights of the first layer d0 and the consecutive ones d1...dn.
