The title compound, C16H20N2O2S2, crystallizes with two enanti-omers (A and B) in the asymmetric unit. The most noticeable difference between these two mol-ecules is the relative orientation of the benzo-thia-zole rings, with S-C-C-S torsion angles of -19.4 (2) (mol-ecule A) and 100.6 (1)° (mol-ecule B). The amide structure of the thia-zolidinone rings leads to inter-molecular hydrogen-bonded dimers of the R and S enanti-omers.
