N′-[(E)-1-(4-Bromo­phen­yl)ethyl­idene]-4-hy­droxy-2-methyl-1,1-dioxo-2H-1,2-benzothia­zine-3-carbohydrazide

The six-membered heterocycle in the title compound, C(18)H(16)BrN(3)O(4)S, adopts a sofa conformation. Intra­molecular N—H⋯N and O—H⋯O hydrogen bonds stabilize the mol­ecular conformation by forming a five- and a six-membered ring, respectively. The crystal packing is stabilized by inter­molecular C...

Sumario:The six-membered heterocycle in the title compound, C(18)H(16)BrN(3)O(4)S, adopts a sofa conformation. Intra­molecular N—H⋯N and O—H⋯O hydrogen bonds stabilize the mol­ecular conformation by forming a five- and a six-membered ring, respectively. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen bonds.
