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.
