4-Amino-5-(4-bromo-benzo-yl)-3-(benzo[ d ]thia-zol-2-yl)-2-[(2',3',4',6'-tetra- O -acetyl-β-d-galacto-pyran-osyl-)sulfanyl]-thio-phene.

In the title compound, C 32 H 29 BrN 2 O 10 S 3 , the benzo-thia-zole and thio-phene ring systems subtend an inter-planar angle of 7.43 (12)°. The NH 2 group forms intra-molecular hydrogen bonds to N thia-zole and O carbon-yl . The S galactose -C thio-phene bond is short [1.759 (2) Å]. The mol-ecules are connected to form ribbons parallel to the b axis by two 'weak' hydrogen bonds and a short N amino ⋯S galactose contact.
