Deskripsi

In the title compound, C13H10ClFO3S2, the two-ring system is essentially planar, the mean plane of the benzene ring being inclined at 6.0 (2)° to the plane of the remaining four atoms. The ethylsulfanyl group is almost coplanar with the two rings [dihedral angle = 6.4 (2)°], while the carboxylate group is almost perpendicular to it [dihedral angle = 72.4 (2)°]. In the crystal structure, intermolecular C—H...O and C—H...F hydrogen bonds link the molecules in a stacked arrangement along the a axis.
