4-(4-Fluoro­phen­yl)-3-(pyridin-4-yl)-1-(2,4,6-trichloro­phen­yl)-1H-pyrazol-5-amine

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.
