Adsorption models of [Mn^III₆Cr^III]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...d_n.
