In the title compound, C 7 H 4 ClNO 4 , the molecules form centrosymmetric dimers through OÐHÁ Á ÁO hydrogen bonds. The dimers are connected by CÐHÁ Á ÁO hydrogen bonds to form molecular tapes. Disorder of the H atom in the OÐ HÁ Á ÁO hydrogen bond is suggested.
In the title compound, C 13 H 12 N 2 O 3 , the dihedral angle between the benzene rings is 65.8 (2) . The crystal structure is stabilized by N-HÁ Á ÁO hydrogen bonds and C-HÁ Á Á interactions.
