摘要：

In the title compound, C18H18F2N2O3S, the piperazine ring adopts a chair conformation. The dihedral angle between the sulfonyl-bound benzene ring and the best fit plane throught the six non-H atoms of the piperazine ring is 69.4 (2)(degrees), while those between the fluorobenzene and sulfonyl rings and the fluorobenzene and piperazine rings are 30.97 (2) and 75.98 (2)(degrees), respectively. In the crystal, molecules are connected to form a tetrameric unit through C-H...O hydrogen bonds. The structure is further stabilized by weak intermolecular C-H...F interactions, generating C(8) and C(7) chains running along [100].
