(Z)-3-Chloromethylidene-5,6-dimethoxy-2-methyl-2,3-dihydro-1,2-benzothiazole 1,1-dioxide

Abstract

The title compound, C11H12ClNO4S, adopts a Z configuration about the C=C double bond. The benzisothiazole system is essentially planar [maximum deviation of 0.235 (2) Å for the S atom]. In the crystal, the molecules stack parallel to each other in the b-axis direction, with interplanar spacings for the benzene and thiazole rings ranging from 3.402 (2) to 3.702 (2)A.
