Abstract
In the molecule of the title compound, C10H9Br2NO3S, the S atom is four-coordinated in distorted tetrahedral configuration. The heterocyclic thiazine ring adopts a twist conformation. An intramolecular C-H center dot center dot center dot O hydrogen bond results in the formation of a non-planar five-membered ring. In the crystal structure, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into infinite chains along the c axis.
