novel molybdenumcomplexbearing a 4-[3,5-bis(trifluoromethyl)phenyl]pyridine-based PNP-type pincer ligand, based on the bond dissociation free energies of the N−H bonds in molybdenum-imide complexesbearing various substituted PNP pincer ligands. The complex worked as an excellent catalyst toward ammonia formation, where up to 3580 equivalents of ammonia were formed based on the molybdenum atom of
