1-[1-(3-Methyl-phen-yl)-5-phenyl-4-phenyl-sulfonyl-1H-pyrazol-3-yl]ethanone.

ABSTRACT: Both the acetyl and phenyl substituents of the central pyrazole ring in the title compound, C(24)H(20)N(2)O(3)S, are twisted with respect to the pyrazole ring, with the twist involving the phenyl ring being greater [67.4?(1) and 29.6?(2)°]. The tolyl substituent is disordered over two positions in a 1:1 ratio; the mean planes of the aromatic ring are aligned at 67.7?(3) and 69.4?(3)° with respect to the pyrazole ring.

Project description:The asymmetric unit of the title compound, C(23)H(18)N(2)O(3)S, contains two mol-ecules with comparable geometries. In one mol-ecule, the pyrazole ring forms dihedral angles of 61.65 (11), 47.88 (11) and 63.20 (14)° with the three benzene rings. The corresponding values for the other mol-ecule are 77.19 (11), 43.55 (11) and 63.56 (15)°. In the crystal, both mol-ecules are linked into inversion dimers by pairs of C-H⋯S hydrogen bonds, generating R(2) (2)(14) loops in each case.

Phen-yl(3-methyl-1-phenyl-sulfonyl-1H-indol-2-yl)methanone.

Project description:In the title compound, C(22)H(17)NO(3)S, the N atom of the indole ring system deviates by 0.031?(3)?Å from a least-squares plane fitted through all nine non-H ring atoms. The geometry around the S atom can be described as distorted tetra-hedral. As a result of the electron-withdrawing character of the phenyl-sulfonyl groups, the N-Csp(2) bond lengths are longer than the typical mean value for N atoms with a planar configuration.

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

Project description: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.

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

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.

1-{2-[(E)-2-(2-Nitro-phen-yl)ethen-yl]-1-phenyl-sulfonyl-1H-indol-3-yl}ethanone.

Project description:In the title compound, C24H18N2O5S, the S atom has a distorted tetra-hedral configuration, with bond angles varying from 105.11?(7) to 119.98?(8)°. As a result of the electron-withdrawing character of the phenyl-sulfonyl group, the N-Csp (2) bond lengths [1.414?(2) and 1.413?(2)?Å] are slightly longer than the reported value of 1.355?(14)?Å for N atoms with a planar configuration. The indole moiety is essentially planar, with a maximum deviation of 0.0177?(14)?Å for the N atom. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 85.70?(7)° with the mean plane of the indole moiety. The mol-ecular structure features intra-molecular C-H?O hydrogen bonds, which generate S(6) and S(12) ring motifs. In the crystal, adjacent mol-ecules are linked via C-H?O hydrogen bonds, forming infinite C(7) chains running along the a-axis direction. The crystal packing also features C-H?? inter-actions, which form a three-dimensional structure.

4-[(4-Chloro-phen-yl)(5-hydr-oxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:In the the title compound, C(27)H(23)ClN(4)O(2), the chloro-phenyl ring forms dihedral angles of 77.70 (9) and 86.65 (9)°, respectively, with the pyrazol-3-one and pyrazole rings. The phenyl rings attached to the pyrazole rings are twisted away from them [dihedral angles 33.80 (9) and 40.34 (10)°]. An intramolecular O-H⋯O hydrogen bond generates an S(8) ring motif. The mol-ecules are linked into chains running along the c axis by N-H⋯N hydrogen bonds, and the chains are cross-linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions involving the chloro-phenyl ring.

Phen-yl(1-phenyl-sulfonyl-1H-indol-2-yl)methanone.

Project description:The asymmetric unit of the title compound, C(21)H(15)NO(3)S, contains two crystallographically independent mol-ecules. As a result of the electron-withdrawing character of the phenyl-sulfonyl groups, the N-Csp(2) bond lengths are slightly longer than the anti-cipated value of approximately 1.35 Å for N atoms with planar configurations. Both unique S atoms have a distorted tetra-hedral configuration. In each mol-ecule, the indole ring system is essentially planar (r.m.s. deviations for all non-H atoms of 0.020 and 0.023 Å). In one mol-ecule, the indole ring system makes dihedral angles of 65.7 (8) and 73.4 (8)°, respectively, with the benzene and phenyl rings [62.2 (7) and 72.1 (7)°, respectively, in the other mol-ecule].

1-(4-Methyl-phen-yl)-3-phenyl-1H-pyrazol-5-yl 4-nitro-benzene-sulfonate.

Project description:In the title mol-ecule, C(22)H(17)N(3)O(5)S, the pyrazole ring is planar (r.m.s. deviation = 0.018?Å) and forms dihedral angles of 21.45?(10) and 6.96?(10)° with the N- and C-bound benzene rings, respectively. Supra-molecular layers in the bc plane are formed in the crystal via C-H?O and ?-? inter-actions involving the sulfonamide benzene ring inter-acting with the N- and C-bound benzene rings [centroid-centroid distances = 3.790?(2) and 3.730?(2)?Å, respectively]. The crystal studied was found to be a merohedral twin (twin law 1 0 0.678, 0 -1 0, 0 0 -1), the fractional contribution of the minor component being approximately 36%.

1-{3-(4-Methyl-phen-yl)-5-[5-(2-nitro-phen-yl)furan-2-yl]-4,5-di-hydro-1H-pyrazol-1-yl}ethanone.

Project description:In the title compound, C22H19N3O4, the dihedral angle between the furan and pyrazole rings is 82.73?(19)° while the dihedral angles between the furan and pyrazole rings and their attached benzene rings are 31.93?(18) and 1.88?(18)°, respectively. In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds generate R 2 (2)(16) loops. In addition, weak C-H?? and aromatic ?-? stacking [minimum centroid-centroid distance = 3.5374?(17)?Å] inter-actions are observed.
