The crystal structure of N ‐ (2,3,4,6‐Tetra‐ O ‐acetyl‐β‐ D ‐glycosyl)‐thiocarbamic benzoyl hydrazine (C 22 H 27 N 3 O 9 S) was determined by X‐ray diffraction method. The hexopyranosyl ring adopts a chair conformation. All the ring substituents are in the equatorial positions. The acetoxyl‐methyl group is in synclinal conformation. The S atom is in synperiplanar conformation while the benzoyl hydrazine moiety is anti ‐periplanar. The thiocarbamic moiety is almost coplanar with the benzoyl hydrazine group. There are two intramolecular hydrogen bonds and one intermolecular hydrogen bond for each molecule in the crystal structure. The molecules form a network structure through intermolecular hydrogen bonds.
