Synthesis and Crystal Structure of 1-(2-Nitro- benzenesulfonyl)-piperidin-4-yl-diphenyl-methanol

The title compound 1-(2-nitro-benzenesulfonyl)-piperidin-4-yl-diphenyl-methanol was synthesized by the condensation of [piperidin-4-yl]-diphenyl-methanol with 2-nitro benzene sulfonylchloride in methylene dichloride as solvent and triethylamine as the base. The product obtained was characterized by spectroscopic techniques and the structure was investigated by X-ray crystallography. The compound crystallizes in the monoclinic crystal class in the space group Pc with cell parameters a = 9.2360(4) A, b = 10.7750(8) A, c = 13.4110(8) A, β = 124.162(4)°, V = 1104.35(12)A3 for Z = 2. The structure reveals that the piperidine ring is in a chair conformation. There is a large discrepancy around the bond angles of the piperidine N atom. The geometry around the S atom is distorted tetrahedron.
