title: 1-(3,4-Di-fluoro-benz-yl)-4-(4-methyl-phenyl-sulfon-yl)piperazine.
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 di-fluoro-benzene rings are 74.96 and 86.16°, respectively. In the crystal, mol-ecules are stacked along the a axis through weak C-H⋯O and C-H⋯F inter-actions.
