The crystal structure of pyridinyl-2-methylene-4-aminobenzoic acid, C₁₃H₁₀N₂O₂, shows the expected stereochemistry trans around the C=N double bond. On the other hand, hydrogen bonds play an important role concerning geometrical aspects of molecules in the solid state. From this point of view, the methanimine moiety of the disubstituted C=N bond provides intermolecular interactions through hydrogen bonds with polarizable acceptor atoms included on the terminal substituents. The molecule shows an intermolecular COOH…N hydrogen bond. The unequal distribution of the double-bond character among the C and N atoms of the methanimine group indicates delocalization of the π electrons over the C=N moiety towards the terminal substituents.
