| Abstract: | The structure of N-(2,3,4,6-Tetra-O-acetyl-β-D-glycosyl)thiocarbamoyl methylene diamine, C16H25N3O9S has been determined by X-ray diffraction method. It crystallizes in the monoclinic system, space group P2l, with lattice parameters a = 7.6560(2), b = 10.3113(3), c = 14.1813(1)Å, β = 100.879 (2)o, and Z = 2. The hexapyranosyl ring adopts a chair conformation. All the ring substituents are in the equatorial position. The acetoxylmethyl group is in the gauche- gauche conformation. The S atom is in synperiplanar conformation, while the N-C-N-C linkage is antiperiplanar. The N-H...O intermolecular hydrogen bonds link the molecules into infinite chains and these are connected by C-H...O interaction. |
