Abstract: 2-Phenyl-1-phenylthio-1-(tetrahydropyran-2-ylthio)propan-2-ol, C20H24O2S2, was synthesized as a mixture of four diastereoisomers. An isomer which crystallizes in the centrosymmetric monoclinic space group P21/c with the relative configuration (1S*,2R*,2'R*) is presented. Intermolecular hydrogen bonds between the hydroxyl group and the O atom of the tetrahydropyran ring of a neighbouring molecule [OO 2.751 (2) Å] form zigzag chains in the c-axis direction. The tetrahydropyran ring has a chair conformation with an axial S-side chain.
