Web2,2'-Bipyridine is a chemical compound with the formula (C 5 H 4 N) 2. This colorless solid, commonly abbreviated bipy (pronounced "bip-ee"), is a widely used isomer of bipyridine. It is a bidentate chelating ligand, forming complexes with many transition metals. Ruthenium complex and platinum complexes of bipy exhibit intense luminescence ... Bipy forms a wide variety of complexes. Almost always, it is a bidentate ligand, binding metal centers with the two nitrogen atoms. Examples: • Mo(CO)4(bipy), derived from Mo(CO)6. • RuCl2(bipy)2, a popular precursor to mixed ligand complexes.
