(E)-5-Phenyl-N'-(1-phenyl-ethyl-idene)-1H-pyrazole-3-carbohydrazide.

ABSTRACT: In the mol-ecule of the title compound, C(18)H(16)N(4)O, the intra-molecular N-H?N hydrogen bond results in the formation of a planar five-membered ring, which is also co-planar with the adjacent five-membered ring, being oriented at a dihedral angle of 1.23?(3)°. The dihedral angles formed by the planar pyrazole ring with the adjacent phenyl ring and the other phenyl ring are 7.29 and 11.21°, respectively. The dihedral angle between the two phenyl rings is 18.07°. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules.

Project description:The title compound, C22H22FN3O, crystallized with two independent mol-ecules (A and B) in the asymmetric unit; these are linked by a pair of N-H?O hydrogen bonds, forming a pseudo-centrosymmetric dimer with an R (2) 2(10) motif.

Ethyl 1-(4-methyl-phen-yl)-5-phenyl-4-phenyl-sulfon-yl-1H-pyrazole-3-carboxyl-ate.

Project description:The title compound, C(25)H(22)N(2)O(4)S, features a tetra-substituted pyrazole ring. The dihedral angles formed between the five-membered ring (r.m.s. deviation = 0.007?Å) and the N- and C-bound phenyl rings are 48.10?(7) and 72.01?(7) °, respectively, indicating that the planes through the residues are significantly twisted from the plane through the heterocycle. The ester-CO(2) group is also twisted out of this plane, with an O-C-C-N torsion angle of -29.04?(11)°. The sulfonyl-O atoms lie to one side of the pyrazole plane and the sulfonyl-phenyl ring to the other. The dihedral angle between the two ring planes is 70.63?(7) °. Supra-molecular arrays are formed in the crystal structure sustained by C-H?O and C-H??(pyrazole) inter-actions and methyl-C-H??(N-bound benzene) contacts.

N'-Benzoyl-5-methyl-1,3-diphenyl-1H-pyrazole-4-carbohydrazide.

Project description:In the title compound, C24H20N4O2, the pyrazole ring makes dihedral angles of 47.57?(10)° and 30.56?(11)° with its N-bound and C-bound phenyl groups, respectively.

The torsion angles between the carbonyl groups and their adjacent pyrazole and phenyl rings are 125.89?(19) and 164.22?(17)°, respectively. In the crystal, pairs of mol-ecules are linked by N-H?O hydrogen bonds into R 2 (2)(10) ring motifs, which in turn link to form chains that propagate parallel to the c-axis direction.

5-Methyl-N'-[(3Z)-2-oxo-2,3-dihydro-1H-indol-3-yl-idene]-1-phenyl-1H-1,2,3-triazole-4-carbohydrazide.

Project description:In the title compound, C18H14N6O2, the benzene ring is slightly twisted out of the plane of the 1,2,3-triazole ring (r.m.s. deviation = 0.010?Å), forming a dihedral angle of 6.20?(13)°. The nine non-H ring atoms of the fused five- and six-membered ring system are almost coplanar (r.m.s. deviation = 0.032?Å). The near coplanarity in the central residue is consolidated by an intra-molecular bifurcated N-H?(O,N) hydrogen bond. The conformation about the N=C bond is Z. In the crystal, supra-molecular chains along [101] are sustained by N-H?O hydrogen bonds and C-H?O inter-actions. These are consolidated into a three-dimensional architecture by C-H?? and ?-? inter-actions; the latter occur between centrosymmetrically related 1,2,3-triazole rings [centroid-centroid distance = 3.6056?(14)?Å].

1-Phenyl-1H-pyrazole-4-carbaldehyde.

Project description:In the title mol-ecule, C(10)H(8)N(2)O, the five- and six-membered rings form a dihedral angle of 10.14?(9)°. The aldehyde group is almost coplanar with the pyrazole ring to which it is connected [O-C-C-C torsion angle = -179.35?(17)°]. In the crystal, inversion dimers are linked by four C-H?O inter-actions as the carbonyl O atom accepts two such bonds. The dimeric aggregates are linked into supra-molecular layers in the ac plane by C-H?? and ?-? [ring centroid(pyrrole)?ring centroid(phen-yl) = 3.8058?(10)?Å] inter-actions.
