4-(3-Methyl-5-phenyl-1H-pyrazol-1-yl)benzenesulfonamide
With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. 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 pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to...

Significant twists between the aromatic rings are evident in the structure of the title compound, C(16)H(12)F(3)N(3)O(2)S. With reference to the pyrazole plane, the N- and C-bound benzene rings form dihedral angles of 57.12 (11) and 29.75 (11)°, respectively. The dihedral angle between the benzene rings is 52.82 (11)°. The presence of N-H⋯O(sulfonamide) and N-H⋯N(pyrazole) hydrogen bonds lead t...
متن کامل[1-(4-Chlorophenyl)-5-hydroxy-3-phenyl-1H-pyrazol-4-yl](thiophen-2-yl)methanone
In the title compound, C(20)H(13)ClN(2)O(2)S, the chloro-phenyl, phenyl and thienoyl rings are oriented at dihedral angles 17.84 (7), 53.13 (8) and 34.03 (8)°, respectively, to the central pyrazole ring. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, pairs of bifurcated O-H⋯O hydrogen bonds link mol-ecules into inversion dimers with R(2) (2)(12) graph-set motifs.

In the title compound, C(26)H(24)BrN(3)O(2), the isoxazolidine ring adopts an envelope conformation, the ring N atom deviating from the mean plane of the other four atoms by an angle of 0.286°. The orientation of the phenyl ring is +sp and the bromophenyl ring is +sc relative to the attached pyrazole ring; the dihedral angles between the least-squares planes of the pyrazole and the attached phe...

In the title compound, C18H15N3O2, the benzo-furan ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, mol-ecules are linked by weak N-H⋯N, N-H⋯O and C-H⋯O inter-actions, generating edge-fused R 4 (4)(20), and R...
