Abstract

The asymmetric unit of title compound, C28H38O18S2·C4H8O, comprises one disulfide-bridged sugar molecule and one solvent molecule. No significant differences in structural parameters are found between the present structure and the previously determined unsolvated form [Brito, López- Rodríguez, Bényei & Szilagyi (2006). Carbohydr. Res. 341, 2967-2972]. The compounds are characterized by a compact structure with spatial proximity of the two pyranosyl rings. One of the carbonyl atoms is disordered over two sites [site occupancy = 0.69 (7) for major component] and the displacement parameters for the THF species are unsually large. © 2008.
