CARBON DIOXIDE ACTIVATION BY LITHIUM METAL: PART 1. INFRARED SPECTRA OF Li + CO2 - , Li + C2O4 - AND Li22 + CO22 - IN INERT-GAS MATRICES.

Article abstract of DOI:10.1021/ja00350a025

Lithium atoms react spontaneously with carbon dioxide to form Li** plus CO//2** minus and Li//2**2** plus CO//2**2** minus in inert gas matrices. Reaction of Li and CO//2 in an argon matrix leads also to the formation of Li** plus C//2O//4** minus . Two geometrical isomers of Li** plus CO//2** minus have been isolated in solid argon. One has a ring structure in which the metal interacts symmetrically with the two oxygen atoms, while in the second isomer the lithium atom is bonded to only one of the two oxygens.
