Figure 3

(a) STM image of the Ag(110) surface after deposition of DITP. Islands of DITP in a zigzag structure (blue arrow) as well as islands of iodine (green arrow). Lattice directions are overlaid (\({V}_{sample-bias}\) = 1.8 V, \({I}_{set-point}\) = 100 pA). (b) Close-up of DITP island in (a) shown by the blue arrow. Green arrows show areas of disorder in the island (\({V}_{sample-bias}\) = 1.0 V \({I}_{set-point}\) = 50 pA). (c) Average of 10 line profiles taken along the different zigzag line sections (red and blue lines in (b) and inset). Molecule-molecule separation is consistent with proposed metal-organic structure. (d) Close-up of metal-organic structure with overlay of proposed model and measured dimensions (\({V}_{sample-bias}\) = 1.0 V \({I}_{set-point}\) = 50 pA). (e) Adsorption model for DITP on Ag(111) with overlaid molecular lattice (red) and surface lattice vectors (top right).
