摘要
The crystal structure ofN-(2,3,4,6-tetra-O-acetyl-β-D-glycosyl)-thiocarbamic benzoyl hydrazine ( C_(22)H_(27)N_3O_9S) wasdetermined by X-ray diffraction method. The hexopyranosyl ring adopts a chair conformation. All thering suhstituents are in the equatorial positions. The acetoxyl-methyl group is in synclinalconformation. The S atom is in synperiplanar conformation while the benzoyl hydrazine moiety isanti-periplanar. The thiocarbamic moiety is almost coplanar with the benzoyl hydrazine group. Thereare two intramolecular hydrogen bonds and one intermolecular hydrogen bond for each molecule in thecrystal structure. The molecules form a network structure through intermolecular hydrogen bonds.
