(S)-2-[(S)-2,2,2-Trifluoro-1-hydroxyethyl]-1-tetralone

The crystal structure of the title compound, C12H11F3O2, was elucidated by low-temperature single-crystal X-ray diffraction. The enantiopure compound crystallizes in the Sohncke space group P21 and features one molecule in the asymmetric unit. The structure displays intermolecular O—H...O hydrogen bonding, which links the molecules into infinite chains propagating parallel to [010]. The absolute configuration was established from anomalous dispersion.
