title: Crystal structures of rare disaccharides, α-D-glucopyranosyl β-D-psicofuranoside, and α-D-galactopyranosyl β-D-psicofuranoside.
abstract: The crystal structures of α-D-glucopyranosyl β-D-psicofuranoside and α-D-galactopyranosyl β-D-psicofuranoside were determined by a single-crystal X-ray diffraction analysis, refined to R(1)=0.0307 and 0.0438, respectively. Both disaccharides have a similar molecular structure, in which psicofuranose rings adopt an intermediate form between (4)E and (4)T(3). Unique molecular packing of the disaccharides was found in crystals, with the molecules forming a layered structure stacked along the y-axis.
