| Popis: | International audience; The activation of carbon dioxide by three different Mo‐diimine complexes [Mo(CO) 4 (L)] (L = bipyridine (bpy), 1,10‐phenantroline (phen) or pyridylindoziline (py‐indz)) has been investigated by electrochemistry and spectroelectrochemistry. Under inert atmosphere, monoreduction of the complexes is ligand‐centred and leads to tetracarbonyl [Mo(CO) 4 (L)] •− species, whereas double reduction induces CO release. Under CO 2 , [Mo(CO) 4 (L)] complexes undergo unexpected coupled chemical‐electrochemical reactions at the first reduction step, leading to the formation of reduced CO 2 derivatives. The experimental results obtained from IR, NIR and UV‐Vis spectroelectrochemistry, as well as DFT calculations, demonstrate an electron‐transfer reaction whose rate is ligand‐dependent. |
