3-(4-Chloro­phen­yl)-5-(4-fluoro­phen­yl)-4,5-dihydro-1H-pyrazole-1-carbothio­amide

In the title compound, C(16)H(13)ClFN(3)S, the pyrazole ring adopts an envelope conformation with the methine C atom being the flap atom. The chloro- and fluoro­benzene rings are twisted out of the plane of the pyrazole ring [dihedral angles = 15.12 (11) and 80.55 (10)°, respectively]. The amine group is orientated towards a ring N atom, forming an intra­molecular N—H⋯N hydrogen bond. This H atom also forms a hydrogen bond to the F atom, which along with N—H⋯S hydrogen bonding leads to a supra­molecular chain along the c axis. Connections between chains of the type Cl⋯π lead to a layer in the bc plane.
