1-{4-Chloro-2-[2-(2-fluoro-phen-yl)-1,3-dithio-lan-2-yl]phen-yl}-2-methyl-1H-imidazole-5-carbaldehyde

There are two mol-ecules in the asymmetric unit of the title imidazole derivative, C(20)H(16)ClFN(2)OS(2). In one mol-ecule, the dithiol-ane 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-chloro-phenyl and 2-fluoro-phenyl rings, respectively, in one mol-ecule; in the other mol-ecule, the corresponding angles are 82.72 (9) and 17.39 (10)°. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions and these linked mol-ecules are stacked along the b axis by π-π inter-actions with a centroid-centroid distance of 3.4922 (11) Å. In addition, π-π inter-actions between the imidazole and 2-fluoro-phenyl 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 inter-actions. 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.
