5-(4-Fluoro­phen­yl)-3-(4-methyl­phen­yl)-4,5-dihydro-1H-pyrazole-1-carbothio­amide

The central pyrazole ring in the title compound, C(17)H(16)FN(3)S, adopts an envelope conformation with the methine C atom bearing the 4-fluoro­phenyl substituent as the flap atom. Whereas the tolyl ring is slightly twisted out of the least-squares plane through the pyrazole ring [dihedral angle = 1...

Sumario:The central pyrazole ring in the title compound, C(17)H(16)FN(3)S, adopts an envelope conformation with the methine C atom bearing the 4-fluoro­phenyl substituent as the flap atom. Whereas the tolyl ring is slightly twisted out of the least-squares plane through the pyrazole ring [dihedral angle = 13.51 (11)°], the fluoro­benzene ring is almost perpendicular [dihedral angle = 80.21 (11)°]. The thio­amide group is almost coplanar with the N—N bond of the ring [N—N—C—N torsion angle = 1.2 (3)°] and the amine group forms an intra­molecular hydrogen bond with a ring N atom. In the crystal, supra­molecular double layers in the bc plane are formed via N—H⋯S, N—H⋯F and C—H⋯F inter­actions.
