Ligation of Carbon Monoxide at Iron and Cobalt Single-Metal-Atom Sites: Competition for the +1 Oxidation State in a Surface-Confined Organic Network
Cobalt coordination to a FeTPyP monolayer on graphene yields a two-dimensional FeTPyP–Co metal-organic network, stabilizing highly reactive Fe(I) sites within a biomimetic coordination architecture. The assembly process triggers an electronic reorganization that activates the pristine Fe(II) centers, enabling competiti...
