Abstract: In the title compound, C18H20F2N2O2S, the central piperazine ring adopts a chair conformation. The dihedral angle between the two benzene rings is 40.20°, whereas those between the piperazine ring (considering the best fit plane through all the non-H atoms) and the sulfonyl-bound benzene and di­fluoro­benzene rings are 74.96 and 86.16°, respectively. In the crystal, mol­ecules are stacked along the a axis through weak C-H...O and C-H...F inter­actions.
