3-Methyl-1-phenyl-4-[(Z)-phen-yl(4-acetamido-anilino)methyl-idene]-1H-pyrazol-5(4H)-one.

ABSTRACT: In the title compound, C(25)H(22)N(4)O(2), the dihedral angles between the central pyrazole ring and the phenyl and benzene rings are 37.01 (3), 75.58 (7) and 49.67 (8)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) motif. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into a zigzag chain extended along the b axis.

(4Z)-4-[(4-Chloro-anilino)(phen-yl)methyl-ene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

Project description: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 [mean deviation = 0.0398 (5) Å] of the central unit, generating an S(6) ring motif. The crystal packing is stabilized by van der Waals forces.

The crystal packing exhibits no classical inter-molecular contacts.
