In the title compound, C(25)H(16)F(2)N(2)O, the pyrazole ring is almost planar (r.m.s. deviation = 0.028 Å) and makes a dihedral angle of 5.86 (11)° with the indazole benzene ring. The dihedral angle between the pyrazole ring and the unsubstituted phenyl ring is 28.19 (11)°. The dihedral angles between the unsubstituted phenyl and the two fluoro-phenyl groups are 57.69 (10) and 18.01 (10)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯F inter-actions, forming infinite chains along the b axis with graph-set motif R(3) (2)(19). The crystal structure is further consolidated by π-π stacking [centroid-centroid distances = 3.5916 (13) and 3.6890 (13) Å] and C-H⋯π inter-actions.
在标题化合物C₂₅H₁₆F₂N₂O中,吡唑环几乎呈平面状(均方根偏差 = 0.028 Å),与吲唑苯环形成的二面角为5.86 (11)°。吡唑环与未取代苯环之间的二面角为28.19 (11)°。未取代苯环与两个氟苯环之间的二面角分别为57.69 (10)°和18.01 (10)°。在晶体中,分子通过分子间N - H⋯O和C - H⋯F相互作用相连,沿着b轴形成具有R(3) (2)(19)图形集模式的无限链。晶体结构通过π - π堆积[质心 - 质心距离 = 3.5916 (13) 和3.6890 (13) Å]和C - H⋯π相互作用进一步巩固。
