The title compound, C13H6Cl3F3N4O, was synthesized by the reaction of 5-amino-1-[2,6-dichloro-4-(trifluoro­meth­yl)phen­yl]-1H-pyrazole-3-carbonitrile and 2-chloro­acetyl chloride. The five-membered pyrazole ring makes a dihedral angle of 71.5 (3)° with the benzene ring. The –CF3 group is disordered by rotation, and the F atoms are split over two sets of sites with occupancies of 0.59 (2) and 0.41 (2). The crystal structure features weak C—H...O and N—H...N inter­actions involving the carbonyl and cyano groups as acceptors.

The title compound, C12H8Cl2N4O, was synthesized by the reaction of 5-amino-1-(4-chloro­phen­yl)-1H-pyrazole-3-carbonitrile and 2-chloro­acetyl chloride. The dihedral angle between the pyrazole and benzene rings is 30.7 (3)°. In the crystal structure, strong N—H...O hydrogen bonds link the mol­ecules into chains along [001]. C—H...N hydrogen bonds are also present.
