We present infrared spectra of [CoO(CO2)n]− and [NiO(CO2)n]− clusters and interpret them in the framework of computational results employing density functional theory. We find that both [CoO(CO2)n]− and [NiO(CO2)n]− clusters are generally composed of the same core isomers. The dominant isomers consist of an η2 CO2 ligand and a CO3 moiety that can be bound to the metal atom with monodentate (η1) or bidentate (η2) connectivity. Minor structural isomers observed are composed of a C2O4 moiety with a lone oxygen atom or a CO3 unit.
