Abstract: The crystal structure of C I2HIsNO7 has been determined at room temperature. Crystals are tetragonal, space group P432~2, Z = 8, with a -- 12.039 (1), c = 17.979 (4)A. 1304 observed reflexions contributed to the full-matrix least-squares refinement to give R -- 0.075. The pyranose ring displays a slightly distorted chair with 4C~ conformation and all the substituents (furanose ring, NO 2 and OH groups) are equatorial. The reported configuration can be considered as the absolute configuration from the absence of epimerization at the anomeric atom. The packing of the structure can be described by a three-dimensional hydrogen-bonding scheme.
