The mol-ecule of the title compound, C(23)H(20)N(4)O, assumes a non-planar conformation in which the pyrazolone ring forms dihedral angles of 10.33 (11), 65.34 (11) and 63.52 (10)° with the three benzene rings. In the crystal, the mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds, generating chains parallel to the b axis. The secondary amino group is involved in an intra-molecular N-H⋯O hydrogen bond.
标题化合物C(23)H(20)N(4)O的分子呈非平面构象,其中吡唑啉酮环与三个苯环形成的二面角分别为10.33 (11)°、65.34 (11)°和63.52 (10)°。在晶体中,分子通过分子间N-H⋯N氢键相连,形成平行于b轴的链。仲氨基参与了分子内N-H⋯O氢键的形成。
