Abstract: In the title benzoate derivative, C13H6ClN3O8, the planes of the benzene rings form a dihedral angle of 73.59 (7)°. The central ester unit forms an angle of 20.38 (12)° with the chloro-substituted benzene ring. In the crystal, molecules are linked by weak C-HO interactions, forming helical chains along  and .
