2,2' -bipyridine is one of the isomers of bipyridine, colorless solid. It is a didentate chelated ligand that forms complexes with many metal ions and is therefore useful as a REDOX indicator. Complexes with ruthenium and platinum have strong luminescence properties and may have potential applications. Its derivatives can be obtained by dehydrogenation of pyridine with Raney nickel.
