4-[(Z)-Allyl­amino­(phen­yl)methyl­ene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one

The title compound, C(20)H(19)N(3)O, exists in a keto–enamine tautomeric form. The pyrazolone ring makes dihedral angles of 20.52 (10) and 77.73 (5)° with the two phenyl rings and an intra­molecular N—H⋯O hydrogen bond occurs. A weak inter­molecular C—H⋯O hydrogen bond is observed in the crystal str...

description The title compound, C(20)H(19)N(3)O, exists in a keto–enamine tautomeric form. The pyrazolone ring makes dihedral angles of 20.52 (10) and 77.73 (5)° with the two phenyl rings and an intra­molecular N—H⋯O hydrogen bond occurs. A weak inter­molecular C—H⋯O hydrogen bond is observed in the crystal structure. The allyl group is disordered over two positions, with site-occupancy factors of 0.533 (5) and 0.467 (5).
