(5E)-1-Benzyl-5-(3,3,3-tri­chloro-2-oxo­propyl­idene)pyrrolidin-2-one

In the crystal structure of the title compound, C₁₄H₁₂Cl₃NO₂, no classical hydrogen-bonding inter­actions are observed. The methyl­ene fragments of the benzyl groups participate in non-classic hydrogen-bond inter­actions with the carbonyl O atoms of neighboring mol­ecules, generating co-operative centrosymmetric dimers with R₅⁵(10) ring motifs. The overall mol­ecular 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.
