Abstract:A new complex of N-(2,3,4,6-tetra-O-acetyl-beta,D-glucopyranosyl) thiocarbamic 2,4-dihydroxy benzoyl hydrazine monohydrate, C22H27N3O11S center dot H2O, has been synthesized and its structure is determined by X-ray crystallography and TG/DTG. The compound crystallizes in the orthorhombic system, space group P4(3)2(1)2, with cell dimensions of a 12.0199 (7), b = 12.0199 (7), c = 38.877 (3) angstrom, V = 5616.9 (6) angstrom(3) and Z = 8. The hexopyranosyl ring adopts a C-4 conformation. All the substituents are in equatorial positions. The molecules are linked into a three-dimensional framework by intermolecular interactions. The atoms 03, 07, O9 and C14 show positional disorders.
