A (PNP)Co(i)methyl diamagnetic complex formally loses an H atom from the pincer ligand, exhibiting a long-range metal–ligand cooperation in what may be considered as an unusual example of ‘C–H cleavage’. Spectroscopic data indicate that the product is a neutral Co(i) complex with a radical delocalized in the ligand backbone.
