Quaterpyridine

Quaterpyridine refers to a family of pyridine derivatives with the formula (NC₅H₄-C₅H₃N)₂. These compounds can also be viewed as bipyridine decorated with two pyridyl substituents. Several isomers are known. All are colorless solids. One particular isomer, 2,2':6',2'':6'',2'''-quaterpyridine, a derivative of 2,2'-bipyridine has attracted interest because it is a potential tetradentate ligand in coordination chemistry.^[1]
