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.

Abstract

In the title compound, C32H29BrN2O10S3, the benzo-thia-zole and thio-phene ring systems subtend an inter-planar angle of 7.43 (12)°. The NH2 group forms intra-molecular hydrogen bonds to Nthia-zole and Ocarbon-yl. The Sgalactose-Cthio-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 Namino⋯Sgalactose contact.
