چکیده
In the title compound, C23H18N6O5·C2H6O, all three benzene rings lie in an approximate plane [maximum deviation = 0.2688 (16) Å] that makes an angle of 53.56 (3)° with the plane of the pyrazolone ring. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, the ethanol solvent mol-ecule links adjacent mol-ecules through N-H⋯O-H⋯O hydrogen bonds, leading to an infinite chain along the c-axis direction. The ethyl group of the ethanol solvent mol-ecule is disordered over two set of sites in a 0.762 (5):0.238 (5) ratio.

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...
