Abstract: A new complex of N-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-thiocarbamic 4-hydroxy-benzoyl hydrazine dihydrate, C22H27N3O10S·2H2O, was synthesized and its structure was determined by X-ray crystallography and TG/DTG methods. The compound belongs to the orthorhombic system, which crystallizes in space group P212121, with a=1.0275(3), b=1.3419(4), c=2.0234(6), V=2.7899(16) nm3, and Z=4. The hexopyranosyl ring adopts a 4C1 conformation. All the substituents are at equatorial positions. The molecules are linked into a three-dimensional framework via intermolecular interactions. Atoms O5 and O9 show positional disorders.
