2-(2, 5-Dichlorophenylhydrazono)glutaric acid and 2-(3, 5-dichlorophenylhydrazono)glutaric acid

The title compounds, C11H10Cl2N2O4, are constitutional isomers which exhibit similar molecular geometry. The configuration about the N=C bond is E in both molecules. The same packing pattern was found in both structures. Hydrogen-bonded dimers, formed around the inversion centres via O-H ... O interactions of carboxyl groups, are connected into infinite chains. The intramolecular N-H ... Cl hydrogen bond observed only in the 2, 5-dichlorophenyl derivative contributes to the planarity of the molecule.
