Among the various homogenous electrocatalysts, especially Re(bpy)(CO) 3 Cl and [Ni(cyclam)] 2+ were shown to be highly efficient for the selective conversion of CO 2 to CO at moderate potentials. However, a purposeful combination of a Re I tricarbonyl unit with a cyclam ligand hitherto received no attention. Herein, we report on a series of cyclam based Re complexes comprising the original {N 4 } as well as heteroatom‐altered ligand frameworks, describe their synthesis, reveal their coordination behavior and furthermore investigate their performance towards the electrochemical CO 2 reduction.
