Abstract:
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.
