In the title compound, C14H8Cl2FN3O2, the 4-fluorophenyl ring and the nitro-substituted benzene ring form a dihedral angle of 63.29 (8)degrees. In the crystal, molecules are linked by C-H center dot center dot center dot O hydrogen bonds into chains running parallel to the c axis. The crystal packing is further stabilized by C-Cl center dot center dot center dot pi, C-F center dot center dot center dot pi and N-O center dot center dot center dot-pi interactions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H center dot center dot center dot O/O center dot center dot center dot H (15.5%), H center dot center dot center dot H (15.3%), Cl center dot center dot center dot H/H center dot center dot center dot Cl (13.8%), C center dot center dot center dot H/H center dot center dot center dot C (9.5%) and F center dot center dot center dot H/H center dot center dot center dot F (8.2%) interactions.
