In the title mol-ecule, C(15)H(13)ClF(3)N(3)O(3), the pyrazole and benzene rings form a dihedral angle of 77.6 (3)°. In the crystal, mol-ecules related by translation along the a axis are linked into chains via C-H⋯O hydrogen bonds. The crystal packing is stabilized further by weak π-π [centroid-centroid distance = 3.734 (6) Å] and dipole-dipole inter-actions [C⋯O = 3.174 (2) Å].
在标题分子C(15)H(13)ClF(3)N(3)O(3)中,吡唑环和苯环形成的二面角为77.6 (3)°。在晶体中,沿a轴平移相关的分子通过C—H⋯O氢键连接成链。晶体堆积通过弱的π-π[质心-质心距离 = 3.734 (6) Å]和偶极-偶极相互作用[C⋯O = 3.174 (2) Å]进一步稳定。
