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

Abstract

In the crystal structure of the title compound, C14H 12Cl3NO2, no classical hydrogen-bonding interactions are observed. The methylene fragments of the benzyl groups participate in nonclassic 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.
