The syntheses of five 1D coordination polymers containing the sawhorse-type unit [Ru-2(mu-OAc)(2)(CO)(4)] linked by various bridging N,N-donor ligands are reported. Various pi-conjugated linkers, such as trans-[1,2-bis(N-methyl)imidazol-2-yl]ethylene (trans-bie), pyrazine (pyz), 4,4-bipyridine (4,4-bipy) and 1,2-bis(4-pyridyl)ethylene (bpe) as well as the aliphatic linker 1,4-diazabicyclo[2.2.2]octane (DABCO), were applied in the syntheses. The formation of 1D coordination polymers was proven by crystal structure determinations of two of the polymeric materials. The geometries and electronic structures of all polymers were analysed further by CASSCF/CASPT2 and DFT calculations based on monomeric model compounds. Finally, first attempts regarding deposition of the 1D chain, the sawhorse fragment and/or the ligands on a highly ordered pyrolytic graphite surface, analysed by STM measurements, are also reported.
