2-(Prop-2-en-yl)-1,2-benzisothia-zol-3(2H)-one 1,1-dioxide.

ABSTRACT: In the title compound, C(10)H(9)NO(3)S, the benzisothia-zole group is almost planar (with a maximum deviation of 1.61?Å). The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds, forming a chain of mol-ecules along b.
