_refine_ls_abs_structure_details
; The absolute configuration was assigned to agree with
that of its precursor (S)-trifluorolactic acid at the chiral centre C2.
This compound has no atom heavier than Si and analyzed by
Mo radiation so that Flack parameter is not listed.
Friedel pairs were merged before refinement.
