(1 S ,2 S )-2-[( S )-2,2,2-Tri-fluoro-1-hy-droxy-eth-yl]-1-tetra-lol.

The crystal structure of the title enanti-opure tetralol derivative {systematic name: (1,2)-2-[()-2,2,2-tri-fluoro-1-hy-droxy-eth-yl]-1,2,3,4-tetra-hydro-naph-thalen-1-ol}, CHFO, synthesized by asymmetric transfer hydrogenation, was elucidated by low-temperature single-crystal X-ray diffraction. The enanti-opure compound crystallizes in the Sohncke space group 222 with one mol-ecule in the asymmetric unit and features intra-molecular as well as inter-molecular O-H⋯O hydrogen bonding. The absolute configuration was established from anomalous dispersion effects.
