The electronic properties of a trimetallic molecule, [{Cp*(dppe)Fe(C≡C-)}3(1,3,5-C6H3)] (Fe3), are characterized to explore potential uses of these molecules in molecular-electronic devices. Scanning tunneling microscopy (STM) at 77 K under ultra-high vacuum is used to study the adsorption of Fe3 on the Au(111) surface. Neutral Fe3 and mixed-valence species (Fe3+ and Fe32+) are investigated, and STM images are shown to be sensitive to the intramolecular distribution of charge. Experimental data are compared to simulated theoretical results and tip-molecule manipulation is also explored.
