Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C(15)H(19)Br(3)N(2)O(4)S, the thiazine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intramolecular O-H center dot center dot center dot O hydrogen bond, forming a six-membered ring. In the crystal, the molecules are linked into a three-dimensional network through intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot Br and O-H center dot center dot center dot Br hydrogen bonds.
