2,3-Dihydro-1?(6),2-benzothia-zine-1,1,4-trione.

ABSTRACT: In the title compound, C(8)H(7)NO(3)S, the benzene ring is oriented at a dihedral angle of 69.25?(7)° to the S and O atoms of the sulfonyl group. The heterocyclic ring approximates to an envelope, with the N atom in the flap position. In the crystal, mol-ecules are linked by N-H?O(c) (c = carbon-yl) hydrogen bonds, forming C(5) chains along [001]. Two R(2) (2)(10) loops arise from pairs of C-H?O hydrogen bonds and a weak aromatic ?-? stacking inter-action [centroid-centorid separation = 3.8404?(11)?Å] also occurs.

In the title compound, C(8)H(7)NO(3)S, the benzene ring is oriented at a dihedral angle of 69.25 (7)° to the S and O atoms of the sulfonyl group. The heterocyclic ring approximates to an envelope, with the N atom in the flap position. In the crystal, mol-ecules are linked by N-H⋯O(c) (c = carbon-yl) hydrogen bonds, forming C(5) chains along [001].

2-[2-(2-Chloro-phen-yl)-2-oxoeth-yl]-2,3-dihydro-1?(6),2-benzothia-zole-1,1,3-trione.

Project description:The asymmetric unit of the title compound, C(15)H(10)ClNO(4)S, contains two independent conformers wherein the 2-chloro-phenyl group in one is rotated by approximately 180° compared to the other mol-ecule. This affects the S-N-C-C(=O) and N-C-C(=O)-C torsion angles giving vlaues of -87.0?(2) and 158.7?(2)° in one mol-ecule and -104.3?(2) and -173.4?(2)° in the other. The benzisothia-zole ring systems in the two mol-ecules are essentially planar (r.m.s. deviations = 0.017 and 0.010?Å) and form dihedral angles of 73.53?(7) and 73.26?(6)° with the benzene rings. In the crystal, there are weak ?-? inter-actions between the benzene rings of the benzisothia-zole groups and symmetry-related chloro-benzene rings with centroid-centroid distances of 3.6178?(13) and 3.6267?(15)?Å. In addition, pairs of weak inter-molecular C-H?O hydrogen bonds form inversion dimers which are connected by further C-H?O hydrogen bonds into a three-dimensional network.

Project description:In the title mol-ecule, C(24)H(19)NO(6)S, the heterocyclic thia-zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.180 (5) and 0.497 (5) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The benzene rings of the benzothia-zine unit and the meth-oxy-phenyl group are almost coplanar, with the dihedral angle between the mean planes of these rings being 5.9 (2)°, while the benzene ring of the 2-oxo-2-phenyl-ethyl group is inclined at 79.68 (11) and 81.01 (10)°, respectively, to these rings. The mol-ecular structure is consolidated by intra-molecular O-H⋯O and C-H⋯N inter-actions, and the crystal packing is stabilized by weak C-H⋯O hydrogen bonds.
