چکیده
In the title compound, C16H13ClFN3S, the pyrazole ring adopts an envelope conformation with the methine C atom being the flap atom. The chloro- and fluoro-benzene 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 intra-molecular 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 supra-molecular chain along the c axis. Connections between chains of the type Cl⋯π lead to a layer in the bc plane.

In the title compound, C26H23FN6S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The thio-urea group is close to being coplanar with the pyrazole N atoms [N-N-C-S torsion angle = 176.78 (15)°], which allows for an intra-molecular N-H⋯N hydrogen bond; the connected triazole ring is nearly coplanar with this ring [N-C-C-N = -172.65 (19)°]. There is a...

The central pyrazole ring in the title compound, C17H16FN3S, adopts an envelope conformation with the methine C atom bearing the 4-fluoro-phenyl 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 fluoro-benzene ring is almost perpendicular [dihedral angle = 80.21 (11)°]. The thio-a...
