Different catalytic pathways and their potential reaction mechanisms are investigated using a large range of experimental and computational techniques. Sophisticated spectroscopic methods including UV/Vis absorption and pulsed-EPR techniques (2P-ESEEM and HYSCORE) were combined together with DFT calculations to successfully identify a key intermediate in the catalytic cycle of CO2 reduction. The results directly show the formation of a metal–carboxylic acid–CO2 adduct after oxidative addition of CO2 and H+ to a Mn0 carbonyl dimer, an unexpected intermediate.Show less >
