 Abstract: A series of saturated ruthenium cluster carbonyls (Ru(CO)5+ , Ru2(CO)9+ , Ru3(CO)12+ , Ru4(CO)14+ , Ru5(CO)16+ and Ru6(CO)18+ ) has been synthesized in the gas phase and subsequently characterized by infrared spectroscopy. Their size-specific IR spectra in the regions of the carbonyl stretch vibration (1900-2150 cm-1) as well as in the region of the Ru-C-O bending modes (420-620 cm-1) are obtained by infrared multiple photon dissociation spectroscopy. The structures of these cluster carbonyls are assigned by comparison to results from density functional calculations. A multitude of differently activated CO ligands is identified in these cationic cluster carbonyls, reaching from terminal, over non-symmetrically bridging (semi-bridging) ligands with varying degrees of interaction to additional Ru atoms towards symmetrically bridging CO ligands.
