(Z)-3-Methyl-4-[1-(4-methylanilino)propylidene]-1-phenyl-1H-pyrazol-5(4H)-one
In the title mol-ecule, C20H21N3O, the central pyrazole ring forms dihedral angles of 4.75 (9) and 49.11 (9)°, respectively, with the phenyl and methyl-substituted benzene rings. The dihedral angle between the phenyl and benzene rings is 51.76 (8)°. The amino group and carbonyl O atom are involved in an intra-molecular N-H⋯O hydrogen bond. In the crystal, π-π inter-actions are observed between ...

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.

The title compound, C(21)H(23)N(3)O, exists in an enamine-keto form with the amino group involved in an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the phenyl rings is 73.59 (6)°. The five-membered ring is nearly planar, the largest deviation being 0.0004 (7) Å, and makes dihedral angles of 4.81 (6) and 69.81 (5)° wth the phenyl rings. In the crystal, pairs of weak C-H⋯O int...
