We report infrared photodissociation spectra of manganese-CO ₂ cluster anions, [Mn(CO ₂) _n] ^- (n = 2-10) to probe structural motifs characterizing the interaction between Mn and CO ₂ in the presence of an excess electron. We interpret the experimental spectra through comparison with infrared spectra predicted from density functional theory calculations. The cluster anions consist of core ions combining a Mn atom with a variety of ligands, solvated by additional CO ₂ molecules. Structural motifs of ligands evolve with increasing cluster size from simple monodentate and bidentate CO ₂ ligands to oxalate ligands and combinations of these structural themes.
