Bioinspired pentadentate ligand N‐confused porphyrin (NCP) bearing a 2‐mercaptopyridine group and its Ru II and Co III complexes were synthesized. Their structures were revealed by single‐crystal X‐ray crystallographic analysis. Installation of an axial thiopyridine ligand shifts the redox potentials negatively and enhances the catalytic activity largely, which was demonstrated in the cyclopropanation reaction using the Co complex.
