4-Hy-droxy-2-methyl-1,1-dioxo-N-phenyl-2H-1?(6),2-benzothia-zine-3-carboxamide.

ABSTRACT: In the title mol-ecule, C(16)H(14)N(2)O(4)S, the thia-zine ring adopts a twist chair conformation with the N and adjacent C atom displaced by 0.966?(3) and 0.386?(4)?Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The dihedral angle between the mean planes of the benzene rings is 37.65?(10)°. The mol-ecular structure features an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules are linked by N-H?O and C-H?O hydrogen bonds.

Project description: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 42.32?(11)°. In the crystal, mol-ecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers. The dimers are linked via a series of C-H?O inter-actions, leading to the formation of a three-dimensional network.

Methyl 4-hy-droxy-2-isopropyl-1,1-dioxo-2H-1,2-benzothia-zine-3-carboxyl-ate.

Project description:In the crystal structure of the title mol-ecule, C(13)H(15)NO(5)S, the S and N atoms of the thia-zine ring exihibit the maximum deviations from the least-squares plane of 0.3008?(6) and 0.3280?(7)?Å, respectively. The ring therefore adopts a half chair conformation. The thia-zine ring is twisted by an angle of 13.29?(7)° with respect to the aromatic ring. The isopropyl substituent is oriented at a dihedral angle of 53.2?(12)° with respect to the thia-zine ring. An intra-molecular O-H?O hydrogen bond occurs. Inter-molecular hydrogen bonding is observed in the crystal structure.

4-Hy-droxy-2-methyl-1,1-dioxo-2H-1?,2- benzothia-zine-3-carb-oxy-lic acid hemihydrate.

Project description: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 generate R(2) (2)(8) loops. The dimers are consolidated into chains extending along [100] by bridging O-H?O hydrogen bonds from the water mol-ecule. A weak C-H?O hydrogen bond also occurs.
