Manganese carbonyl complexes have become popular homogeneous catalysts for carbon dioxide electro- or photoredn. since the beginning of the 2010s. This article presents a comprehensive survey of all the Mn carbonyl systems reported during the last decade as being active catalysts for CO2 redn., with a comparison of their activity, stability and selectivity under electroredn. and, for some of them, photoredn. conditions. The development of in situ spectroelectrochem. techniques, often backed by DFT calcns., has enabled gaining more insight into the assocd. catalytic mechanisms and reaction intermediates. Though manganese tricarbonyl compds. featuring a bipyridine deriv. have been by far the most studied, alternative Mn coordination spheres have recently been explored, opening a way towards new families of potential catalysts for homogeneous and heterogeneous CO2 redn.
