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