چکیده
The title compound, C(11)H(12)ClNO(4)S, adopts a Z configuration about the C=C double bond. The benzisothia-zole system is essentially planar [maximum deviation of 0.235 (2) Å for the S atom]. In the crystal, the mol-ecules stack parallel to each other in the b-axis direction, with inter-planar spacings for the benzene and thia-zole rings ranging from 3.402 (2) to 3.702 (2) Å.

The title mol-ecule, C(10)H(9)NO(5)S, is composed of two essentially planar units with a dihedral angle of 89.16 (6)° between them. In the crystal structure, there are weak inter-molecular C-H⋯O inter-actions resulting in dimeric pairs of mol-ecules about inversion centres and chains of mol-ecules extended along the a and c axes, thus stabilizing the structure. In addition, benzothia-zole rings...

The title compound, C(11)H(11)NO(3)S, was synthesized by the reaction of benzo[d]isothia-zol-3(2H)-one with isopropanol in toluene. The benzoisothia-zolone ring system is essentially planar, with a mean deviation of 0.018 (2) Å from the least-squares plane defined by the nine constituent atoms. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.
