2-(2-isopropylanilino)pyridine-3-carboxylic acid

b The asymmetric unit of the title compound, C15H16N2O2, contains two molecules and in each of the molecules, the two aromatic rings, lying in two different planes, are bridged by a secondary amino group. This might be due to steric hindrance caused by the isopropyl group. Intra- and intermolecular N - H center dot center dot center dot O hydrogen bonds link the molecules, forming an infinite one-dimensional tape structure; they may be effective in the stabilization of the crystal structure.
