(E)-5-Phenyl-N′-(1-phenylethylidene)-1H-pyrazole-3-carbohydrazide
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°, ...

In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99 (5) and 34.95 (5)°, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H⋯O inter-actions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H⋯N inter-actions.

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 C-N-N-C group that links the two carbonyls has a torsion angle of 81.5 (2)°. 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 cryst...

In the title compound, C24H20N2, the dihedral angles between the pyrazole ring and the pendant phenyl, toluoyl and phenyl-ethenyl rings are 41.50 (8), 4.41 (8) and 31.07 (8)°, respectively. In the crystal, inversion dimers linked by a π-π stacking inter-actions between the phenyl-ethenyl rings are observed [centroid-centroid separation = 3.5857 (9) Å].
