2-{5-[2-(4-Nitro-phen-oxy)phen-yl]-1-phenyl-1H-pyrazol-3-yl}phenol.

ABSTRACT: In the title compound, C(27)H(19)N(3)O(4), the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95?(12)°] due to an intra-molecular O-H?N hydrogen bond, whereas the phenyl ring is tilted by 40.81?(7)° with respect to the plane of the pyrazole ring. The aromatic ring with a nitro-phen-oxy substituent makes a dihedral angle of 54.10?(7)° with the pyrazole ring.

In the title compound, C(27)H(19)N(3)O(4), the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95 (12)°] due to an intra-molecular O-H⋯N hydrogen bond, whereas the phenyl ring is tilted by 40.81 (7)° with respect to the plane of the pyrazole ring. The aromatic ring with a nitro-phen-oxy substituent makes a dihedral angle of 54.10 (7)° with the pyrazole ring. ...[more]

2-[5-(4-Hydroxy-phen-yl)-1-phenyl-1H-pyrazol-3-yl]phenol.

Project description:The title compound, C(21)H(16)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The pyrazole ring and one of the hydr-oxy-substituted benzene rings are approximately coplanar, forming a dihedral angle of 7.5?(3)°. The relative conformation of these rings may be influenced by an intra-molecular O-H?N hydrogen bond. In the crystal structure, inter-molecular O-H?O hydrogen bonds involving different hydr-oxy groups of symmetry-related mol-ecules form extended chains along [201].

[3-(5-Nitro-2-fur-yl)-1-phenyl-1H-pyrazol-4-yl](phen-yl)methanone.

Project description:In the title pyrazole compound, C(20)H(13)N(3)O(4), an intra-molecular C-H?O hydrogen bond generates a seven-membered ring, producing an S(7) ring motif. The essentially planar furan and pyrazole rings [maximum deviations of 0.002?(1) and 0.007?(1)?Å, respectively] are coplanar with each other, forming a dihedral angle of 3.06?(10)°. The pyrazole ring forms dihedral angles of 8.51?(9) and 56.81?(9)° with the two benzene rings. The nitro group is coplanar with the attached furan ring, as indicated by the dihedral angle of 2.5?(3)°. In the crystal packing, inter-molecular C-H?O hydrogen bonds link adjacent mol-ecules into two-mol-ecule-wide chains along the a axis. The crystal packing is further stabilized by weak inter-molecular C-H?? and ?-? inter-actions [centroid-centroid distance = 3.4441?(10)?Å].

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%.

(4-Methyl-phen-yl)[3-(5-nitro-2-fur-yl)-1-phenyl-1H-pyrazol-4-yl]methanone.

Project description:In the title pyrazole compound, C(21)H(15)N(3)O(4), an intra-molecular C-H?O hydrogen bond generates an S(7) ring motif. The essentially planar furan and pyrazole rings [maximum atomic deviations of 0.011?(2) and 0.006?(2)?Å, respectively] make a dihedral angle of 9.21?(11)°. The nitro group is approximately coplanar with the attached furan ring, as indicated by the dihedral angle of 4.5?(2)°. In the crystal structure, inter-molecular C-H?O inter-actions form bifurcated hydrogen bonds, generating R(1) (2)(7) ring motifs. These hydrogen bonds link the mol-ecules into infinite chains along the a axis. The crystal structure is further stabilized by weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.4118?(10)?Å].

5-Bromo-2-[5-(4-nitro-phen-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]pyrimidine.

Project description:In the title pyrazoline compound, C(19)H(14)BrN(5)O(2), the essentially planar pyrazoline and pyrimidine rings [maximum deviations = 0.013 (1) and 0.009 (1) Å, respectively] are inclined slightly to one another, making a dihedral angle of 10.81 (10)°. The nitro-benzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, inter-molecular C-H⋯N contacts link the mol-ecules into dimers in an anti-parallel manner. These dimers are further linked into one-dimensional chains along the b axis via C-H⋯O contacts. The crystal structure is consolidated by three different inter-molecular π-π inter-actions [range of centroid-centroid distances = 3.5160 (11)-3.6912 (11) Å].

(2E)-1-(2,4-Dichloro-phen-yl)-3-[3-(4-nitro-phen-yl)-1-phenyl-1H-pyrazol-4-yl]prop-2-en-1-one.

Project description:In the title compound, C(24)H(15)Cl(2)N(3)O(3), the C=C double bond is E configured. The 1-phenyl-1H-pyrazole moiety is roughly planar (r.m.s. deviation of all fitted non-H atoms = 0.0780?Å), but the mean planes of the two components are inclined at an angle of 9.95?(7)°. The mean plane defined by the non-H atoms of the 1H-pyrazole ring encloses angles of 9.95?(7), 24.54?(6) and 43.02?(6)° with the mean planes of the different benzene rings. In the crystal, C-H?O contacts are present and result in the formation of a double-layer two-dimensional network lying parallel to (110). The shortest inter-centroid distance between two aromatic systems is 3.5455?(7)?Å and is apparent between two pyrazole systems. Further ?-? inter-actions are manifest between a pair of 4-nitro-phenyl rings [centroid-to-centroid distance = 3.6443?(7)?Å] and a pair of 2,4-dichloro-phenyl rings [centroid-to-centroid distance = 3.7797?(7)?Å].

C-H⋯π and π-π [shortest centroid-centroid separation = 3.6546 (9) Å] inter-actions are also observed.
