Abstract
Two unrelated molecules of the title compound, ethyl y-1,2-O-isopropyl idene-alpha-D-xylofuranos-5-C-yl) -1,2,3-triazole-5-carboxylate, C13H1 9N3O6, that are not linked by hydrogen bonding, comprise the asymmetri c unit, There are no unusual bond lengths or angles, The two molecules differ in the degree of rotation around the methylene C atom that joi ns the triazole ring to the sugar part of the molecule, Molecules of t he same conformation form infinite chains joined by hydrogen bonding b etween a HI atom on the hydroxyl group of one molecule and an N atom i n the triazole ring of another molecule generated by the 2(I) screw ax is, Relevant intermolecular N ... O distances are 3.013(3) and 2,806(3 ) Angstrom.
