Crystal structure of (4Z)-4-{[(2-chloro­phen­yl)amino](furan-2-yl)methyl­idene}-3-methyl-1-phenyl-4,5-di­hydro-1H-pyrazol-5-one

In the title compound, C(21)H(16)ClN(3)O(2), the pyrazolone ring and the O=C—C=C—N mean plane [maximum deviation = 0.022 (2) Å] are nearly coplanar, making a dihedral angle 4.56 (8)°, while the phenyl and pyrazole rings subtend a dihedral angle of 19.75 (8)°. The compound is in the enamine–keto form...

Sumario:In the title compound, C(21)H(16)ClN(3)O(2), the pyrazolone ring and the O=C—C=C—N mean plane [maximum deviation = 0.022 (2) Å] are nearly coplanar, making a dihedral angle 4.56 (8)°, while the phenyl and pyrazole rings subtend a dihedral angle of 19.75 (8)°. The compound is in the enamine–keto form and its structure is stabilized by an intra­molecular N—H⋯O hydrogen bond. In the crystal, mol­ecules are linked via C—H⋯N hydrogen bonds, forming chains along [010]. Between the chains there are π–π inter­actions [inter-centroid distances = 3.3902 (9) and 3.5956 (11) Å], linking the chains to form sheets parallel to (10-1).
