چکیده
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-amide 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 intra-molecular hydrogen bond with a ring N atom. In the crystal, supra-molecular double layers in the bc plane are formed via N-H⋯S, N-H⋯F and C-H⋯F inter-actions.

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 essentially planar pyrazole ring (r.m.s. deviation = 0.013 Å) in the title hemisolvate, C(31)H(33)N(7)S·0.5C(3)H(7)NO, is almost coplanar with the pendant thio-urea residue [N-N-C-S torsion angle = -173.2 (4)°] and slightly twisted with respect to the triazole ring [dihedral angle = 7.7 (3)°]. An intra-molecular thio-urea-pyrazole N-H⋯N hydrogen bond, via an S(5) loop, is formed. Supra-mole...
