In the crystal structure of the title compound, C14H12Cl3NO2, no classical hydrogen-bonding inter-actions are observed. The methyl-ene fragments of the benzyl groups participate in non-classic hydrogen-bond inter-actions with the carbonyl O atoms of neighboring mol-ecules, generating co-operative centrosymmetric dimers with R 5 (5)(10) ring motifs. The overall mol-ecular arrangement in the unit cell seems to be highly influenced by secondary non-covalent weak C-Cl⋯π [Cl⋯Cg(phenyl ring) = 3.732 (2) Å] and C-O⋯π [O⋯Cg(pyrrolidine ring) = 2.985 (2) Å] contacts.
在标题化合物C₁₄H₁₂Cl₃NO₂的晶体结构中，未观察到经典的氢键相互作用。苄基的亚甲基片段与相邻分子的羰基O原子参与非经典氢键相互作用，形成具有R⁵(5)(10)环基序的协同中心对称二聚体。晶胞中的整体分子排列似乎受到二级非共价弱C-Cl⋯π [Cl⋯Cg（苯环）= 3.732 (2) Å] 和C-O⋯π [O⋯Cg（吡咯烷环）= 2.985 (2) Å] 接触的高度影响。
