2,2′-Dipyridylamine is an organic compound with the formula (C₅H₄N)₂NH. It consists of a pair of 2-pyridyl groups (C₅H₄N) linked to a secondary amine. The compound forms a range of coordination complexes.[1] Its conjugate base, 2,2′-dipyridylamide, forms extended metal atom chains.[2]

Formation

2,2′-Dipyridylamine can be formed by heating pyridine with sodium amide. Alternatively, 2-aminopyridine can be heated with 2-chloropyridine over barium oxide.[3]
