摘要：
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)degrees to the plane of the remaining four atoms. The ethylsulfanyl group is almost coplanar with the two rings [dihedral angle = 6.4 (2)degrees], while the carboxylate group is almost perpendicular to it [dihedral angle = 72.4 (2)degrees]. In the crystal structure, intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot F hydrogen bonds link the molecules in a stacked arrangement along the a axis.
