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 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.

Keywords: benzothiazole; crystal structure; galactose; thiophene.
