3,3-Dibromo-1-ethyl-1H-2,1-benzo-thiazin-4(3H)-one 2,2-dioxide
Abstract:
In the mol-ecule of the title compound, C(10)H(9)Br(2)NO(3)S, the S atom is four-coordinated in distorted tetra-hedral configuration. The heterocyclic thia-zine ring adopts a twist conformation. An intra-molecular C-H⋯O hydrogen bond results in the formation of a non-planar five-membered ring. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into infinite chains along the c axis.
