(2,3-Difluorophenyl)(4-tosylpiperazin-1-yl)methanone
Abstract
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)°, while those between the fluorobenzene and sulfonyl rings and the fluorobenzene and piperazine rings are 30.97 (2) and 75.98 (2)°, 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].
