5-(4-Fluoro-phen-yl)-3-(4-methyl-phen-yl)-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

Project description: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.

3-Methyl-4-[2-(4-nitro-phen-yl)hydrazin-1-yl-idene]-5-oxo-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

Project description:The asymmetric unit of the title compound, C(11)H(10)N(6)O(3)S, contains two independent mol-ecules, each of which is stabilized by an intra-molecular N-H⋯O hydrogen bond, forming an S(6) ring motif. In one mol-ecule, the pyrazole ring forms a dihedral angle of 10.93 (14)° with the benzene ring. The corresponding dihedral angle in the other mol-ecule is 7.03 (14)°. In the crystal, mol-ecules are linked via pairs of (N,N)-H⋯O bifurcated acceptor bonds which, together with C-H⋯O hydrogen bonds, form sheets parallel to (001).

5-(4-Fluoro-phen-yl)-3-[5-methyl-1-(4-methyl-phen-yl)-1H-1,2,3-triazol-4-yl]-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

Project description:In the title compound, C(20)H(19)FN(6)S, the pyrazole ring has an envelope conformation, with the methine C atom being the flap atom. The dihedral angle between the least-squares plane through the pyrazole and triazole rings is 7.59?(9)°, and the triazole and attached benzene ring form a dihedral angle of 74.79?(9)°. The thio-urea group is coplanar with the pyrazole ring [N-N-C-S torsion angle = -179.93?(11)°], which enables the formation of an intra-molecular N-H?N hydrogen bond. In the crystal, inversion-related mol-ecules associate via N-H?S hydrogen bonds and eight-membered {?HNCS}(2) synthons feature in the crystal packing. These synthons are connected into supra-molecular chains along the a axis via N-H?F hydrogen bonds, and the chains are consolidated into layers in the ab plane via C-H?S and C-H?F contacts.

5-(4-Fluoro-phen-yl)-3-[5-methyl-1-(4-methyl-phen-yl)-1H-1,2,3-triazol-4-yl]-N-phenyl-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

Project description: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 significant twist between the pyrazole ring and attached fluoro-benzene ring [N-C-C-C = -18.8?(3)°] and a greater twist between triazole and attached tolyl ring [dihedral angle = 58.25?(14)°]. In the crystal, supra-molecular chains aligned along [40,10] are consolidated by ?-? inter-actions between the triazole and phenyl rings [centroid-centroid distance = 3.7053?(13)?Å].

3,5-Bis(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazole-1-carbaldehyde.

Project description:In the title mol-ecule, C(16)H(12)F(2)N(2)O, the pyrazole ring adopts a slight envelope conformation with the methyl-ene C atom deviating by 0.114 (3) Å from the mean plane of the other four atoms [maximum deviation = 0.021 (3) Å]. The dihedral angles between the four essentially planar atoms of the pyrazole ring and the fluoro-substituted benzene rings are 2.6 (2) and 82.2 (2)°. The dihedral angle between the two benzene rings is 83.7 (2)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

3,5-Bis(4-bromo-phen-yl)-1-phenyl-4,5-dihydro-1H-pyrazole.

Project description:In the title compound, C(21)H(16)Br(2)N(2), the central pyrazole ring adopts an flattened envelope conformation, with the stereogenic C atom in the flap position. The deviations from planarity for this ring are relatively minor (r.m.s. deviation = 0.045 Å) and the dihedral angles formed with the N- and C(imine)-bound benzene rings are 7.73 (13) and 11.00 (13)°, respectively. By contrast, the benzene ring bound at the chiral C atom is almost orthogonal to the rest of the mol-ecule; the dihedral angle formed between this ring and the pyrazole ring is 79.53 (13)°. In the crystal, the packing is stabilized by C-H⋯N and C-H⋯Br inter-actions.
