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-HN hydrogen bonds, which result in infinite chains parallel to the c axis.
