چکیده
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 complete mol-ecule of the title compound, C(42)H(36)N(6)O(2), is generated by a crystallographic twofold axis with two C atoms of the central phenyl group lying on the axis. In the independent part of the mol-ecule, one amino group is involved in an intra-molecular N-H⋯O hydrogen bond, and the two adjacent phenyl rings are twisted from the plane of the pyrazolone ring with dihedral angles o...
