title: N'-[(E)-1-(4-Bromo-phen-yl)ethyl-idene]-4-hy-droxy-2-methyl-1,1-dioxo-2H-1,2-benzothia-zine-3-carbohydrazide.
abstract: The six-membered heterocycle in the title compound, C(18)H(16)BrN(3)O(4)S, adopts a sofa conformation. Intra-molecular N-H⋯N and O-H⋯O hydrogen bonds stabilize the mol-ecular conformation by forming a five- and a six-membered ring, respectively. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds.
