Gas-phase infrared photodissociation spectra of [V(CO2)(n)](+) complexes revealed three new vibrational bands at 1140, 1800, and 3008 cm(-1) at n = 7, the features of which are retained in the larger clusters (Ricks, A. M.; Brathwaite, A. D.; Duncan, M. A. J. Phys. Chem. A 2013, 117, 11490-11498). However, structural assignment of this intriguing feature remains open. Herein, quantum chemical calculations on [V(CO2)(7)](+) were carried out to identify the structure of the low-lying isomers and to assign the observed spectral features. The comparison of calculated infrared spectra of [V(CO2)(7)](+) with experimental infrared spectra identified the formation of a bent CO2 species, suggesting the ligand-induced activation of CO, by the vanadium cation. The structures and infrared spectra of [Cr(CO2)(7)](+) and [Mn(CO2)(7)](+) were also predicted and discussed.
