## Crystals of the tetrasaccharide, (2,3,4,6-tetra-0acetyl-fi-D-ghxopyranosyl~-(1 + 3)-[2,3,4,6-tetra-O-acetyI+LD-gIucopyranosyI-(1 --t 6)]-(2,4-di-0-acetyl-g\_D-glucopyranosyl)-1 --) 3)-1,2,4,6-tetrad-acetyl$?-n-ghicopyranose, belong to tge monoclinic system, space group P2,, with a = 12.709(4),
Two independent molecules comprise the asymmetric unit of the title compound, C 15 H 19 F 3 O 12 S, which was synthesized by reacting 1,3,4,6-tetra-O-acetyl--d-mannopyranose with trifluoromethanesulfonic anhydride. In one molecule three F atoms and one O of the -SO 2 CF 3 side chains are disordered
