6-Bromo-1-ethyl-1H-2,1-benzothia-zin-4(3H)-one 2,2-dioxide.

In the title compound, C(10)H(10)BrNO(3)S, the S atom is four-coordinated in a distorted tetra-hedral configuration with nearly equal S=O bond distances; the S-C and S-N bond lengths are 1.755 (3) and 1.649 (3) Å, respectively. The heterocyclic thia-zine ring adopts a twist conformation. Adjacent mol-ecules are attached to each other through inter-molecular C-H⋯O hydrogen bonds, forming R(2) (2)(8) and R(2) (2)(14) ring motifs. The mol-ecules are stabilized by intra- and inter-molecular hydrogen bonds, forming a three-dimensional polymeric network.
