Structure of 4,4'-dimethyl-2,2'-bipyridine.

Dimethyl-2,2'-bipyridine can refer to many isomers of 2,2'-bipyridine containing two methyl substituents. All have the formula (CH3)2C10H6N2, but the most common are symmetrical derivatives (CH3C5H3N)2 listed below. These compounds are used as ligands in coordination chemistry and homogeneous catalysis. They are white or colorless. Most are solids except the 3,3' isomer which is a liquid.
