ChEBI: A tridentate heterocyclic ligand that binds metals at three meridional sites giving two adjacent 5-membered MN2C2 chelate rings. | [Description]
A case of occupational dermatitis was reported in a
chemical technician, with no cross reactivity to pyridine
derivatives. | [Uses]
2,2';6',2"-terpyridine is widely utilized in the field of supramolecular chemistry, which is used to manufacture the racks, ladders and grids, helicates, catenanes and dendrimers. It plays an important role as a ligand in coordination chemistry. Its complexes are employed in the oxidation of alcohols, the carbonylation of aromatic compounds and as oxygen-binding molecules. Functionalized terpyridine ligands were used in semiconductors and solar panels. It forms chealate complexes with europium(III) and terbium(III), which is used in protein labelling. | [Synthesis Reference(s)]

As an NNN-tridentate ligand, the 2,2′:6′,2″-terpyridine plays an important role in coordination chemistry. With three coordination sites and low LUMO, terpyridine and its derivatives are one of the typical Pincer ligand and/or non-innocent ligands in transition metal catalysis. Interesting catalytic reactivities have been obtained with these tpy-metal complexes targeting some challenging transformations, such as C–C bond formation and hydrofunctionalization. The 2,2':6':2''-terpyridine ligand has literally shaped the coordination chemistry of transition metal complexes in a plethora of fields.
