2,6-diphenylpyridine-4-carboxylic acid.
The distinctive feature of the crystal structure of 2,6-diphenylpyridine-4-carboxylic acid, C18H13NO2, is the formation of intermolecular O-H...O hydrogen bonds that lead to the formation of centrosymmetric cyclic dimers with R2(2)(8) topology. Molecules related by translation along the b axis exhibit strong pi-pi stacking of aromatic rings, with an average interplanar distance of 3.3 A.
