The conversion of carbon dioxide into chemical fuels is a topic of great interest and recently a lot of different approaches for the electrochemical reduction of this powerful greenhouse gas to more useful products have been reported. We report here for the first time the activity of a dinuclear Re(I) complex [Re-2(mu-Cl)(2)(CO)(6)(mu-diazine)] towards the electrocatalytic reduction of carbon dioxide. It is herein reported its electrochemical characterization in highly aprotic conditions (CH3CN) with a comparison with the analogue mononuclear Re(I) complex, [Re(bpy)(CO)(3)(Cl)]. The dinuclear complex exhibits good performances (TOF0 = 25 h (1)), two times higher than the analogous mononuclear one.

Abstract
The conversion of carbon dioxide into chemical fuels is a topic of great interest and recently a lot of different approaches for the electrochemical reduction of this powerful greenhouse gas to more useful products have been reported. We report here for the first time the activity of a dinuclear Re(I) complex [Re-2(mu-Cl)(2)(CO)(6)(mu-diazine)] towards the electrocatalytic reduction of carbon dioxide. It is herein reported its electrochemical characterization in highly aprotic conditions (CH3CN) with a comparison with the analogue mononuclear Re(I) complex, [Re(bpy)(CO)(3)(Cl)]. The dinuclear complex exhibits good performances (TOF0 = 25 h (1)), two times higher than the analogous mononuclear one.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
