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

Abstract

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 R 5 5(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.

“…In the crystal structure of the title compound, the asymmetric unit is composed by the whole organic molecule, including an additional chloroform solvate ( Fig. 1) and displaying some interesting conformational features (Fabiani Claro Flores et al, 2014). The styrene fragment is planar with r.m.s.…”
