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

ABSTRACT: 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.

4-(3,7-Dimethyl-4-oxo-4,5-dihydro-isoxazolo[4,5-d]pyridazin-5-yl)benzene-sulfonamide.

Project description:The nine-membered fused-ring system of the title pyridazine derivative, C(13)H(12)N(4)O(4)S, is approximately planar (r.m.s. deviation 0.027 Å), and the benzene ring of the phenyl-sulfamide substituent is aligned at 43.5 (1)° to the fused-ring system. The amine group of the sulfonamide substituent forms an N-H⋯O hydrogen bond to the ketonic O atom of two neigboring mol-ecules to generate a chain running along the c axis.

Project description:In the title compound, C(26)H(23)N(5)O(2)S, an intra-molecular N-H⋯O inter-action generates an S(6) ring. The essentially planar S(6) and pyrazole rings [maximum deviations = -0.0270 (14) and 0.0195 (15) Å, respectively] are nearly coplanar, making a dihedral angle of 3.94 (6)°. The S(6) ring makes dihedral angles of 23.79 (6), 78.53 (6) and 67.91 (6)° with the pyrazolone ring, the pyrazole ring and the benzene ring of anti-pyrine, respectively. The structure exhibits a thienyl-ring flip disorder with occupancy factors in the ratio 0.82:0.18.

Project description:In the title compound, C(24)H(26)N(4)O(2), the complete mol-ecule is generated by the application of twofold symmetry. The pyrazole ring is approximately planar [r.m.s. deviation = 0.026 Å] and the benzene ring is twisted out of this plane [dihedral angle = 21.94 (7)°]. A twist in the mol-ecule about the central C-C bond [1.566 (3) Å] is also evident [C-C-C-C torsion angle = 44.30 (14)°]. Supra-molecular layers in the bc plane are formed in the crystal packing via C-H⋯O and C-H⋯π inter-actions.

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.
