Crystal structure of (Z)-4-[1-(4-acetyl­anilino)ethyl­idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

In the solid state, the title compound, C(20)H(19)N(3)O(2), adopts the keto–amine tautomeric form, with the H atom attached to the N atom, which participates in an intra­molecular N—H⋯O hydrogen bond with an S(6) ring motif. The dihedral angles between the pyrazole ring and the phenyl and benzene ri...

description In the solid state, the title compound, C(20)H(19)N(3)O(2), adopts the keto–amine tautomeric form, with the H atom attached to the N atom, which participates in an intra­molecular N—H⋯O hydrogen bond with an S(6) ring motif. The dihedral angles between the pyrazole ring and the phenyl and benzene rings are 3.69 (10) and 46.47 (9)°, respectively. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds, generating C(16) chains propagating in [301]. Weak aromatic π–π stacking inter­actions [centroid–centroid distances = 3.6123 (10) and 3.6665 (10) Å] link the chains into a three-dimensional network.
