Abstract

A strategically designed redox-active ligand ensures proper electronic balance in an Mn(I)–carbonyl template to induce photostability and water solubility. This newly designed Mn–carbonyl complex showcased rapid CO₂ reduction with preferential production of CO (faradaic efficiency ∼88%) as the only C₁ product in pure water, even from a flue gas resource.
