1-Benzhydryl-4-phenylmethane sulfonyl piperazine was synthesized from 1-benzhydryl piperazine with phenylmethane sulfonyl chloride. The product obtained was characterized by 1H NMR, MS and IR techniques and finally confirmed by X-ray crystallography. The title compound C24H26N2O2S, M r = 406.53, crystallizes in the orthorhombic crystal class in the space group Pbca with unit cell parameters a = 11.1240(10)Å, b = 9.4940(15)Å, c = 40.239(4)Å, Z = 8 and V = 4249.7(9)Å3. The structure was solved by direct methods and refined to R 1=0.0561 for 2,445 reflections with [I > 2 σ(I)]. The piperazine ring adopts a chair conformation. The sulfonyl moiety is in a distorted tetrahedral configuration.
