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

Acta Crystallographica Section E Structure Reports Online, 2006
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.
