3-(5-Phenyl-4-phenyl-sulfonyl-1-p-tolyl-1H-pyrazol-3-yl)-1,2-dihydro-quinoxaline.

ABSTRACT: In the crystal structure of the title compound, C(30)H(24)N(4)O(2)S, the dihydro-quinoxaline fused-ring system is disordered over three orientations in a 0.358?(2):0.318?(3):0.324?(3) ratio; the mean planes of the non-H atoms of the disorder components are aligned at 4.0?(3), 11.8?(4) and 41.7?(2)° with respect to the pyrazole ring. The rings of the phenyl and tolyl substituents are aligned at 64.0?(1) and 43.7?(1)° with respect to the pyrazole ring. Weak intermolecular C-H?O hydrogen bonding links the mol-ecules, forming supra-molecular chains running along the a axis.

(Phen-yl)(3-phenyl-sulfonyl-1,2-dihydro-pyrrolo-[1,2-a]quinoxalin-1-yl)methanone.

Project description:In the title mol-ecule, C(24)H(18)N(2)O(3)S, the 13-atom ring system comprising the quinoxaline and fused five-membered ring exhibits an r.m.s. deviation from coplanarity of 0.039 Å, with a maximum deviation of 0.0710 (10) Å for the PhCO-bearing C atom of the five-membered ring. The 10-membered C(8)N(2) quinoxaline ring system has an r.m.s. deviation from coplanarity of 0.022 Å, with a maximum deviation of 0.0403 (9) Å for the C atom involved in the C=C bond in the five-membered ring. The three atoms of the five-membered ring fused to the quinoxaline ring system show deviations of up to 0.118 (2) Å for the PhCO-bearing C atom. C-N bond distances in the quinoxaline ring system of the title mol-ecule deviate from those in unsubstituted quinoxaline. In particular, the two C-N distances to the N atom involved in the five-membered ring are essentially equal, with values of 1.3786 (17) and 1.3773 (16) Å, unlike the difference of nearly 0.06 Å in quinoxaline.

1-(1,5-Diphenyl-4-phenyl-sulfonyl-1H-pyrazol-3-yl)ethanone.

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.

4-[Bis(3-phenyl-1H-pyrazol-1-yl)meth-yl]benzene-1,2-diol.

Project description:The title compound, C(25)H(20)N(4)O(2), is a ditopic ortho-hydro-quinone-based bis-(pyrazol-1-yl)methane ligand. The dihedral angles between the planes of the pyrazole rings and their attached phenyl rings are 17.4?(3) and 5.9?(4)°. The pyrazole rings make a dihedral angle of 87.84?(16)°. One of the two hy-droxy groups forms an intra-molecular hydrogen bond to the other hy-droxy group, whereas the second is involved in an inter-molecular O-H?N hydrogen bond. As a result of these inter-molecular hydrogen bonds, helical chains running along the b axis are formed.

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.

Project description:The title compound, C(30)H(28)N(6)O(2), is a symmetric diimine derived from ortho-dibenzaldehyde. Both C=N bonds are (E)-configured. The terminal N-bonded phenyl groups adopt staggered conformations relative to their respective parent heterocycles, the relevant least-squares planes inter-sect at angles of 32.35?(11) and 38.59?(10)°. In the crystal, C-H?O contacts connect the mol-ecules into chains along the b axis and give rise to a C(1) (1)(14)C(1) (1)(14) and a R(2) (2)(12) pattern on different levels of graph-set analysis. The shortest inter-centroid distance between two centroids was found at 4.2074?(11)?Å between the two five-membered heterocycles.

4-(5-Oxo-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzene-sulfonamide.

Project description:With respect to the aliphatic planar five-membered ring (r.m.s. deviation = 0.011?Å) of the title compound, C(15)H(13)N(3)O(2)S, the phenyl ring is aligned at 6.9?(1)° and the phenyl-ene ring at 2.4?(1)°, so that the three rings are nearly coplanar. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the ketonic O atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.

5-Pentyl-4-phenyl-sulfonyl-1H-pyrazol-3-ol.

Project description:In the title compound, C(14)H(18)N(2)O(3)S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005?(1)?Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09?(5)°. Pairs of inter-molecular N-H?O and O?H?N hydrogen bonds form dimers between neighboring mol-ecules, generating R(2) (2)(10) ring motifs. These dimers are further linked by intermolecular N-H?O and O-H?N hydrogen bonds into two-dimensional arrays parallel to the ac plane. The crystal structure is also stabilized by C-H?? inter-actions.
