Methyl 4-hydroxy-1,1-dioxo-2-(2-phenylethyl)-2H-1λ6,2-benzothiazine-3-carboxylate
In the title compound, C(18)H(17)NO(5)S, the thia-zine ring adopts a half-chair conformation and the dihedral angle between the aromatic rings is 79.41 (6)°. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions resulting in infinite sheets along the b and c axes.

In the title compound, C(10)H(9)NO(5)S·0.5H(2)O, two geometrically different organic mol-ecules are present. The benzene rings and the carboxyl-ate groups are oriented at dihedral angles of 13.44 (4) and 21.15 (18)°. In both mol-ecules, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, both moleucles form inversion dimers linked by pairs of O-H⋯O hydrogen bonds to g...
