ABSTRACT: In the title compound, C(21)H(15)F(2)N(3)O(2), a pyrazole derivative bearing three aromatic substituents, the central five-membered heterocyclic ring makes dihedral angles of 1.77?(14), 3.68?(13) and 72.15?(14)° with the three benzene rings.

Project description:In the asymmetric unit of the title compound, C(17)H(14)F(2)N(2)O, there are three independent mol-ecules (A, B and C) which differ slightly in the relative orientations of the two fluoro-phenyl rings. In mol-ecules A and C one of the fluoro-phenyl rings is disordered over two positions, with occupancy ratios of 0.72?(2):0.28?(2) for mol-ecule A and 0.67?(2):0.33?(2) for mol-ecule C. The dihedral angle between the two fluoro-phenyl rings in the independent mol-ecules lie in the range 70.3?(3)-84.0?(3)°. In the crystal structure, the mol-ecules are linked via inter-molecular C-H?O and C-H?F hydrogen bonds and ??? stacking inter-actions [centroid-centroid distance = 3.7508?(13)?Å], forming a three-dimensional network.

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.

3,5-Dimethyl-1-(4-nitro-phen-yl)-1H-pyrazole.

Project description:In the title pyrazole derivative, C(11)H(11)N(3)O(2), the benzene ring is twisted [dihedral angle = 31.38 (12)°] with respect to the pyrazole ring (r.m.s. deviation = 0.009 Å). The nitro group is effectively coplanar with the benzene ring to which it is attached [O-N-C-C torsion angle = -6.5 (3)°]. Supra-molecular chains along the b axis are formed owing to π-π inter-actions [3.8653 (2) Å] between translationally related mol-ecules involving both the five- and six-membered rings.
