(4Z)-4-[(2-Chloroanilino)(phenyl)methylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one
The title compound, C(23)H(18)ClN(3)O, exists in an enamine-keto form with the amino group involved in an intra-molecular N-H⋯O hydrogen bond. The five-membered ring is nearly planar, the largest deviation being 0.0004 (7) Å, and makes dihedral angles of 16.62 (6), 41.89 (5) and 71.27 (4)° with the phenyl rings. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into supra-molecular ...

The title compound, C(23)H(18)ClN(3)O, was synthesized by the reaction of 4-chloro-aniline and 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one. The terminal benzene rings are twisted at dihedral angles of 48.3 (2), 71.4 (2) and 36.1 (2)° with respect to the central eight-atom methyl-pyrazolone/amino-methyl-ene unit. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation [mea...

In the title compound, C(25)H(23)N(3)O(2), the dihedral angles formed by the pyrazolone ring with the three aromatic rings are 14.59 (7), 79.35 (5) and 87.10 (6)°. Three intra-molecular C-H⋯O, C-H⋯N and N-H⋯O hydrogen-bond inter-actions are present. The crystal structure is stabilized by two weak inter-molecular C-H⋯O and C-H⋯N hydrogen-bond inter-actions.

The title compound, C(20)H(18)N(2)O(4), is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy-phenyl ring mean plane, and by 1.19 (13)° to the phenyl ring. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, making an almost planar (r.m.s. deviation = 0.0243 Å) six membered ring.

In the title compound, C(20)H(19)N(3)O, the dihedral angles formed by the pyrazolone ring with the two phenyl rings are 64.27 (6) and 17.00 (6)°. The mol-ecular structure is stabilized by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds. In the crystal, the mol-ecules are linked into chains along the b axis by inter-molecular C-H⋯O hydrogen bonds.
