In the crystal structure of the title compound, C(21)H(15)N(5)O(2), the planar indolone unit and the pyran ring are almost perpendicular to each other [dihedral angle = 89.41 (2)°], and the pyrazole and phenyl rings are oriented at an angle of 25.74 (1)°. The mol-ecular packing is stabilized by inter- and intra-molecular C-H⋯O, N-H⋯O and C-H⋯π hydrogen bonds.
在标题化合物C(21)H(15)N(5)O(2)的晶体结构中,平面吲哚酮单元和吡喃环几乎相互垂直[二面角 = 89.41 (2)°],吡唑环和苯环的取向角度为25.74 (1)°。分子堆积通过分子间和分子内的C—H⋯O、N—H⋯O和C—H⋯π氢键得以稳定。
