(Z)-4-[(Ethylamino)(furan-2-yl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
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...

The title Schiff base compound, C28H21Cl2N3O, was synthesized by the condensation of 1-(3,4-di-chloro-phen-yl)-3-methyl-4-(4-methyl-benzo-yl)-1H-pyrazol-5(4H)-one with 1-aminona-phthalene. The p-tolyl ring is normal to the pyrazole ring, with a dihedral angle of 88.02 (14)°, and inclined to the naphthalene ring system by 78.60 (12)°. The pyrazole ring is inclined to the naphthalene ring system ...

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...
