Abstract

Surface layer structures of [{Ru2(CO)4(PMe 3)2}(μ-O2CCO2)]4 and [{Ru2(CO)4(PMe3)2}(μ-O 2CCH2CO2)]2 with [Ru 2(CO)4-(PMe3)2] building blocks cis-ligated by either O2CCO2 or O2CCH 2CO2 on highly oriented pyrolytic graphite (HOPG) have been investigated by scanning tunneling microscopy and spectroscopy. STM images of well-ordered assemblies of these two molecules with molecular or submolecular resolution were obtained. These two molecules can adopt an orientation with their Ru-Ru bonds parallel or perpendicular to the substrate surface forming ordered 2D-arrays with different layer structures and tunneling spectra.
