3-Methyl-1,5-diphenyl-4,5-dihydro-1H-pyrazole
In the title compound, C16H16N2, the dihydro-pyrazole ring adopts a shallow envelope conformation, with the C atom bearing the phenyl group displaced by 0.298 (2) Å from the other atoms (r.m.s. deviation = 0.015 Å). The dihedral angles between the four near coplanar atoms of the central ring and the N- and C-bonded phenyl groups are 13.49 (13) and 82.22 (16)°, respectively.

In the title compound, C(22)H(18)N(2)O, the pyrazole ring is almost planar (r.m.s. deviation = 0.0098 Å) and its mean plane makes dihedral angles of 62.2 (2), 87.2 (2) and 8.0 (2)° with the phenyl and benzoyl rings, respectively. The crystal packing is stabilized by π-π stacking inter-actions [centroid-centroid distance = 3.658 (2) Å] and weak inter-molecular C-H⋯O hydrogen bonds.

The title compound, C(30)H(24)N(4), contains two pyrazole rings and four phenyl rings. The pyrazole rings are essentially planar, with maximum deviations of 0.003 (1) and 0.066 (1) Å and make a dihedral angle of 73.43 (6)°. The two pyrazole rings make dihedral angles of 40.08 (6), 9.28 (6), 15.78 (8) and 17.25 (7)° with their attached phenyl rings. In the crystal, there are no significant inter...
متن کاملMethyl 3-methyl-5-oxo-4-(phenylhydrazono)-4,5-dihydro-1H-pyrazole-1-carbodithioate
The title compound, C(12)H(11)N(4)OS(2), has been synthesized by the condensation reaction of 3-oxo-2-(phenyl-hydrazono)butanate and S-methyl-dithio-carbazate. The hydrazine unit and the pyrazole ring are coplanar [dihedral angle 3.8 (4)°] due to extensive conjugation and the N-H⋯O=C intra-molecular hydrogen bond. Two adjacent mol-ecules form dimers due to short C-H⋯O=C [R(2) (2) (18)] and C-H⋯...
متن کامل5-Benzoyl-N,4-diphenyl-4,5-dihydro-1H-pyrazole-3-carboxamide
The title compound, C(23)H(19)N(3)O(2), was synthesized by the 1,3-dipolar cyclo-addition reaction of N-phenyl-α-diazo-acetamide and chalcone. In the mol-ecule, the pyrazoline ring assumes an envelope conformation. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
