2,4,6-Tri­nitro­phenyl 3-chloro­benzoate

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—H...O inter­actions, forming helical chains along [101] and [100].
