Investigation of Cyclam Based Re‐Complexes as Potential Electrocatalysts for the CO ₂ Reduction Reaction

Among the various homogenous electrocatalysts, especially Re(bpy)(CO)3Cl and [Ni(cyclam)]2+ were shown to be highly efficient for selective conversion of CO2 CO at moderate potentials. However, a purposeful combination ReI tricarbonyl unit with cyclam ligand hitherto received no attention. Herein, we report on series based Re complexes comprising original {N4} as well heteroatom-altered frameworks, describe their synthesis, reveal coordination behavior furthermore investigate performance towards electrochemical reduction.
