Mn(bpy)‐type complexes bearing local proton source catalyse the electrochemical reduction of CO 2 . Depending on the strength of the Brønsted acid added to the solution, CO or formate are produced. Spectroelectrochemical studies under Ar and CO 2 atmospheres show fast solvolysis and the dimer formation is suppressed, providing an atypical reduction mechanism of Mn I catalysts. Spectroscopic evidence of Mn hydride formation supports the existence of different electrocatalytic CO 2 reduction pathways. For more information, see the Full Paper by R. Gobetto, C.
