Project description:In the crystal structure of the title compound, C(9)H(9)NO(3)S, there is distorted tetra-hedral geometry around the S atom. The sulfonyl group is almost normal to the benzene ring, while the carbonyl O atom and methyl C atom are on opposite sides of this ring. The heterocyclic ring adopts a half-boat conformation with the S atom out of the plane. The mol-ecules are dimerized by hydrogen bonding involving the benzene ring and the sulfonyl group. These dimers are linked to each other in the same way. There is an intra-molecular hydrogen bond between a methyl C-H group and a sulfonyl O atom, and a ?-? inter-action between the aromatic rings of two dimers at a centroid-to-centroid distance of 3.6373?(13)?Å.

1-Ethyl-1H-2,1-benzothia-zin-4(3H)-one 2,2-dioxide.

Project description:In the title compound, C(10)H(11)NO(3)S, there is distorted tetra-hedral geometry around the S atom. The heterocyclic thia-zine ring adopts a half-chair conformation. The ethyl and sulfonyl groups form dihedral angles of 82.53?(13) and 88.91?(9)°, respectively, with the plane formed by the benzothia-zine ring, excluding the S atom; the S atom and the ethyl group lie on opposite sides of the ring. The mol-ecules are linked into dimers by inter-molecular C-H?O hydrogen bonds involving benzene C-H and carbonyl O atoms, thus forming eight-membered rings. The dimers are linked into chains via inter-actions of a similar type. There is an intra-molecular C-H?O hydrogen bond.

Project description:In the title compound, C(10)H(10)BrNO(3)S, the S atom is four-coordinated in a distorted tetra-hedral configuration with nearly equal S=O bond distances; the S-C and S-N bond lengths are 1.755?(3) and 1.649?(3)?Å, respectively. The heterocyclic thia-zine ring adopts a twist conformation. Adjacent mol-ecules are attached to each other through inter-molecular C-H?O hydrogen bonds, forming R(2) (2)(8) and R(2) (2)(14) ring motifs. The mol-ecules are stabilized by intra- and inter-molecular hydrogen bonds, forming a three-dimensional polymeric network.
