In the title mol-ecule, C(25)H(18)Cl(2)N(2)O(2), the dihedral angles between the pyrazole ring and its N- and C-bonded benzene rings are 8.28 (11) and 40.89 (10)°, respectively. The dihedral angle between the benzene rings is 39.03 (11)°. The title mol-ecule exists in a trans conformation with respect to the acyclic C=C bond. In the crystal, mol-ecules are linked into inversion dimers by pairs of inter-molecular C-H⋯O hydrogen bonds, generating R(2) (2)(14) loops.
在标题分子C(25)H(18)Cl(2)N(2)O(2)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8.28 (11)°和40.89 (10)°。苯环之间的二面角为39.03 (11)°。标题分子相对于无环C=C键以反式构象存在。在晶体中,分子通过分子间C-H⋯O氢键对连接成反演二聚体,形成R(2) (2)(14)环。
