1-[3-(4-Fluoro-phen-yl)-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

ABSTRACT: In the title compound, C(17)H(15)FN(2)O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20?(5)°. In the crystal, a pair of C-H?O hydrogen bonds link neighbouring mol-ecules, forming an inversion dimer. The crystal structure is further consolidated by C-H?? inter-actions and by a ?-? inter-action with a centroid-centroid distance of 3.7379?(6)?Å.

In the title compound, C(17)H(15)FN(2)O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20 (5)°. In the crystal, a pair of C-H⋯O hydrogen bonds link neighbouring mol-ecules, forming an inversion dimer. The crystal structure is further consolidated by C-H⋯π inter-actions and by a π-π inter-action with a centroid-centroid distance of 3.7379 (6) Å. ...[more]

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 π⋯π stacking inter-actions [centroid-centroid distance = 3.7508 (13) Å], forming a three-dimensional network.

Project description:The title mol-ecule, C(18)H(18)N(2)O(2), is V-shaped with the pyrazoline moiety being inclined to the adjacent phenyl ring by an angle of 6.49?(9)°, while the 4-meth-oxy-substituted ring is inclined to the pyrazoline ring by 82.99?(9)°. In the crystal, adjacent mol-ecules are linked by C-H?O inter-actions, forming chains propagating in [100]. There are also C-H?? inter-actions involving adjacent mol-ecules and those related by an inversion center.

1-{5-[4-(Hex-yloxy)phen-yl]-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl}ethanone.

Project description:The crystal structure of the title compound, C(23)H(28)N(2)O(2), is composed of discrete mol-ecules with bond lengths and angles quite typical for pyrazoline derivatives of this class. The plane containing the pyrazoline unit is nearly planar with the mean plane of the phenyl ring at the 3-position, making a dihedral angle of 1.96 (3)°. The crystal packing is stabilized by weak C-H⋯π inter-actions involving both of the aromatic rings.

Project description:In the title compound, C(25)H(20)N(2)O, the pyrazoline ring is nearly planar [maximum atomic deviation = 0.0254?(17)?Å]; but the anthracene ring system is distorted from a coplanar structure [maximum atomic deviation = 0.181?(3)?Å], the dihedral angle between the outer benzene rings being 10.68?(13)°. The pyrazoline ring is almost perpendicular to the mean plane of the anthracene ring system [dihedral angle = 76.94?(8)°], but nearly coplanar with the phenyl ring [dihedral angle = 1.63?(7)°]. ?-? stacking is observed between parallel benzene rings of adjacent anthracene units, the face-to-face distance being 3.27?(3)?Å. Weak intra-molecular C-H?N hydrogen bonding also occurs.

1-[3-(2,4-Dichloro-5-fluoro-phen-yl)-5-(3-methyl-2-thien-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

Project description:In the title mol-ecule, C(16)H(13)Cl(2)FN(2)OS, the dihedral angle between the thio-phene and benzene rings is 80.34 (12)°. The pyrazoline ring is in an envelope conformation, and the plane through the four coplanar atoms makes dihedral angles of 85.13 (9) and 6.89 (10)° with the thio-phene and benzene rings, respectively. The C and O atoms of the acetyl group are nearly coplanar with the attached pyrazoline ring. In the crystal structure, inversion dimers arise from pairs of inter-molecular C-H⋯O hydrogen bonds. A short inter-molecular Cl⋯S contact of 3.4250 (13) Å is also found.

2-[3-(4-Chloro-phen-yl)-5-(4-fluoro-phenyl)-4,5-dihydro-1H-pyrazol-1-yl]-4-phenyl-1,3-thia-zole.

Project description:In the title compound, C24H17ClFN3S, the pyrazole ring is almost planar (r.m.s. deviation = 0.030?Å). With the exception of the methine-bound benzene ring, which forms a dihedral angle of 85.77?(13)° with the pyrazole ring, the remaining non-C atoms lie in an approximate plane (r.m.s. deviation = 0.084?Å) so that overall the mol-ecule has a T-shape. In the crystal, centrosymmetrically related mol-ecules are connected via ?-? inter-actions between pyrazole rings [centroid-centroid distance = 3.5370?(15)?Å] and these stack along the a axis with no specific inter-actions between them.

2-[5-(4-Fluoro-phen-yl)-3-(4-methyl-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]-4-phenyl-1,3-thia-zole.

Project description:In the title compound, C25H20FN3S, two independent mol-ecules comprise the asymmetric unit, which differ in the relative orientation of the fluoro-benzene ring with respect to the pyrazole ring to which it is attached [dihedral angles = 89.39?(17) and 75.23?(16)° in the two mol-ecules]. Each pyrazole ring adopts an envelope conformation with the methine C atom being the flap atom. There are additional twists in the mol-ecules, e.g. between the five-membered rings [dihedral angles = 18.23?(16) and 17.84?(16)°] and between the thia-zole and attached phenyl ring [10.26?(16) and 20.87?(15)°]. Overall, each mol-ecule has a T-shape. In the crystal, mol-ecules are connected into a three-dimensional architecture by weak C-H?? inter-actions.
