The Crystal Structure of N-[(2E)-3-(4-Chlorophenyl)prop-2-en-1-yl]-4-methoxy-N-methylbenzenesulfonamide

The title compound C­ 17 H 18 ClNO 3 S crystallizes in the monoclinic P2 1 /c space group with unit cell parameters a = 15.040 (3)Å, b = 9.151 (6) Å, c = 13.868 (7) Å, ? = 116.38 (5)°. Chlorophenyl and methoxyphenyl ring planes are approximatelyperpendicular and the two moieties form an angle of 82.2°. The crystal packing is stabilized by ?-? and Cl-? interactions,which occur between parallel methoxyphenyl and chlorophenyl moieties. Dipolar intermolecular contacts, mainly involvingthe oxygen atoms and C-H, also contribute to the crystal network
