In the title mol-ecule, C(24)H(16)Cl(2)N(2)O, the dihedral angles between the pyrazole ring and its N- and C-bonded phenyl rings are 7.06 (10) and 53.15 (10)°, respectively. The dihedral angle between the two pendant rings is 52.32 (10)°. The mol-ecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, inversion dimers occur in which each mol-ecule is linked to the other by two C-H⋯O hydrogen bonds to the same acceptor O atom. There are also short Cl⋯Cl contacts [3.3492 (9) Å] and C-H⋯π inter-actions.
在标题分子C₂₄H₁₆Cl₂N₂O中，吡唑环与其N键合和C键合的苯环之间的二面角分别为7.06 (10)°和53.15 (10)°。两个侧环之间的二面角为52.32 (10)°。该分子相对于无环C=C键呈反式构象。在晶体中，形成了反演二聚体，其中每个分子通过两个C—H⋯O氢键与同一个受体O原子相连，与另一个分子相连。还存在短的Cl⋯Cl接触 [3.3492 (9) Å] 和C—H⋯π相互作用。
