Fig. 6. Electron density differences (Δn) of the Au(IMe)2 adsorbed on Au(111) from (a) the free biradical IMe and the Au(111) with the respective adatoms or (b) the isolated Au(IMe)2 complex and the pristine Au(111) surface. Left: One-dimensional representation averaged along the surface plane. Note that H and N atoms are vertically displaced for clarity. Here z is the distance from the Au(111) surface. Right: Three-dimensional representations with red and blue representing regions of enhancement and depletion of electron density, respectively.
