Bipyridine

Bipyridines are a family of organic compounds with the formula (C5H4N)2, consisting of two pyridyl (C5H4N) rings. Pyridine is an aromatic nitrogen-containing heterocycle. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. Bipyridines, especially the 4,4' isomer, are mainly of significance in pesticides.[1]

The six possible regioisomers of bipyridine: (1) 2,2′-bipyridine; (2) 2,3′-bipyridine; (3) 2,4′-bipyridine; (4) 3,3′-bipyridine; (5) 3,4′-bipyridine; (6) 4,4′-bipyridine

Six isomers of bipyridine exist, but two are prominent. 2,2′-bipyridine, also known as bipyridyl, dipyridyl, and dipyridine, is a popular ligand in coordination chemistry[2][3]
