Abstract
There are two molecules in the asymmetric unit of the title imidazole derivative, C20H16ClFN2OS2. In one molecule, the dithiolane ring is disordered over two positions in a 0.849 (9):0.151 (10) ratio. The imidazole ring makes dihedral angles of 79.56 (9) and 18.45 (9)° with the 4-chlorophenyl and 2-fluorophenyl rings, respectively, in one molecule; in the other molecule, the corresponding angles are 82.72 (9) and 17.39 (10)°. In the crystal, molecules are linked by weak C—H⋯O interactions and these linked molecules are stacked along the b axis by π–π interactions with a centroid–centroid distance of 3.4922 (11) Å. In addition, π–π interactions between the imidazole and 2-fluorophenyl rings are also observed, with centroid–centroid distances of 3.4867 (11) and 3.4326 (10) Å. The crystal is further consolidated by weak C—H⋯π interactions. Cl⋯S [3.5185 (8) Å], C⋯O [3.192 (3) Å] and C⋯C [3.326 (2)–3.393 (3) Å] short contacts are also observed.
