title: (2,3-Difluoro-phen-yl)(4-tosyl-piperazin-1-yl)methanone.
abstract: In the title compound, C(18)H(18)F(2)N(2)O(3)S, 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)°, while those between the fluoro-benzene and sulfonyl rings and the fluoro-benzene and piperazine rings are 30.97 (2) and 75.98 (2)°, respectively. In the crystal, mol-ecules are connected to form a tetra-meric unit through C-H⋯O hydrogen bonds. The structure is further stabilized by weak inter-molecular C-H⋯F inter-actions, generating C(8) and C(7) chains running along [100].
