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

ABSTRACT: 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 ?-? inter-actions with a centroid-centroid distance of 3.4922?(11)?Å. In addition, ?-? 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?? 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.
