Abstract: In the title compound, C20H12Cl3FN4, the pyrazole ring forms dihedral angles of 47.51 (9), 47.37 (9) and 74.37 (9)° with the directly attached 4-fluoro­phenyl, pyridine and 2,4,6-trichloro­phenyl rings, respectively. Only one of the two amino H atoms is involved in hydrogen bonding. The crystal packing is characterized by N-H...N hydrogen bonds, which result in infinite chains parallel to the c axis.
