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.

The molecule of the title compound, C9H7IN4OS, is almost planar (r.m.s. deviation = 0.0373 Å). In the molecule, N—H...N and N—H...O hydrogen bonds generate, respectively,S(5) andS(6) ring motifs. In the crystal, molecules are linkedviaN—H...O hydrogen bonds, forming chains propagating along [010]. These chains are linkedviaS...I contacts [3.4915 (16) Å], forming sheets lying parallel to (100). A region of disordered electron density, probably a disordered tetrahydrofuran solvent molecule, was treated using the SQUEEZE routine inPLATON[Spek (2009).Acta Cryst.D65, 148–155]. The formula mass and unit-cell characteristics were not taken into account during refinement.
