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