The title compound, C14H18F3NO8, was produced through conjugation of 1,3,4-tri-O-acetyl-2-azidodeoxy-α,β-L-fucose with trifluoroacetyl chloride in the presence of bis(diphenylphosphino)ethane in tetrahydrofuran at room temperature. The X-ray crystal structure reveals that the β-anomer of the product mixture crystallizes from ethyl acetate/hexanes. The compound exists in a typical chair conformation with the maximum possible number of substituents, four out of five, located in the sterically preferred equatorial positions. The major directional force facilitating packing of the molecules are N—H...O hydrogen bonds involving the amide moieties of neighboring molecules, which connect molecules stacked along thea-axis direction into infinite strands with aC11(4) graph-set motif. Formation of the strands is assisted by a number of weaker C—H...O interactions involving the methine and methyl H atoms. These strands are connected through further C—H...O and C—H...F interactions into a three dimensional network
