2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one
The title compound, C(20)H(16)Cl(2)N(4)O, has two mol-ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol-ecule and 56.8 (3)° in the other independent mol-ecule. The amino group of the dihydro-pyrazolone unit of one mol-ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro-pyrazolone system of the other mol-ecule. The resul...

The title compound, C(25)H(19)N(3)O(2), crystallizes as discrete mol-ecules which are well ordered through one intra-molecular N-H⋯O hydrogen bond. Structural analysis indicates that the mol-ecules exist as the amine-one form.

In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol-ecules exist in the keto-enamine form. The pyrazole ring is oriented at 10.59 (4) and 57.98 (5)° to the phenyl and furyl rings, respectively, and the dihedral angle between phenyl and furyl rings is 73.30 (11)°. An intra-molecular N-H⋯O hydrogen bond occurs between imino and carbonyl groups. In the crystal, weak C-H⋯O hydrogen bo...
متن کامل(Z)-4-[(2-Aminoanilino)(phenyl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
The mol-ecule of the title compound, C(23)H(20)N(4)O, assumes a non-planar conformation in which the pyrazolone ring forms dihedral angles of 10.33 (11), 65.34 (11) and 63.52 (10)° with the three benzene rings. In the crystal, the mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds, generating chains parallel to the b axis. The secondary amino group is involved in an intra-molecular N...

In the title compound C(14)H(17)N(3)O(2), the dihedral angle between the rings is 16.68 (13)°. Although the compound crystallizes in the keto form, the possibility of keto-enamine-enol-imine tautomerism is explained by a strong intra-molecular N-H⋯O hydrogen bond.
