1-Ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide

In the title compound, C10H11NO3S, there is distorted tetrahedral geometry around the S atom. The heterocyclic thiazine 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 benzothiazine rin...

Summary:In the title compound, C10H11NO3S, there is distorted tetrahedral geometry around the S atom. The heterocyclic thiazine 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 benzothiazine ring, excluding the S atom; the S atom and the ethyl group lie on opposite sides of the ring. The molecules are linked into dimers by intermolecular 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 interactions of a similar type. There is an intramolecular C-H...O hydrogen bond.
