Oxidizing CO2with superhalogens.
The possibility of oxidizing carbon dioxide molecule using the series of SbnF5n+1(n = 1-3) superhalogen systems was investigated on the basis of quantum chemistry calculations performed using the QCISD and B3LYP methods and the 6-311+G(d)/LANL2DZ basis sets. The Sb3F16species was found to be capable of forming a stable and strongly bound ionic Sb3F16-/CO2+compound when combined with the CO2molecule, whereas the remaining SbF6and Sb2F11species were predicted to form only weakly bound complexes. The conclusions concerning the ionic character of the Sb3F16-/CO2+resulting compound are supported by the discussion of the binding energy values, charge flow between the interacting fragments, and localization of the unpaired electron spin density.
