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. 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.

In the title mol-ecule, C(17)H(16)N(2)O(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.546 (4) and 0.281 (4) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond. The two aromatic rings are inclined to one another by 4...

In the title compound, C(11)H(11)NO(4)S, the thia-zine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intra-molecular O-H⋯O hydrogen bond, forming a six-membered ring. Mol-ecules are linked through weak inter-molecular C-H⋯O hydrogen bonds, resulting in chains lying along the b axis.
