Reactions of 107Ag atoms with CO have been studied in inert hydrocarbon matrices in a rotating cryostat at cryogenic temperatures by EPR and FTIR spectroscopies. AgCO, bent Ag(CO)2, two conformers of Ag(CO)3, and cluster carbonyls Agn(CO)x, where n ≥ 5, are formed in adamantane. Magnetic parameters are reported for these silver carbonyls. IR spectra show the presence of a range of carbon monoxide complexes with single Ag atoms and Ag clusters, but the considerable overlapping of the bands from all these species precludes assignment other than that at 1952 cm-1 to planar Ag(CO)3. In cyclohexane unambiguous EPR or FTIR evidence for mononuclear Ag carbonyls is not obtained, but there are strong complex features in both spectra from a range of Ag cluster carbonyls Agn(CO)x with n = 2-7.
