4-(5-Oxo-5H-1,2,4-dithia­zol-3-yl)phenyl 4-methyl­benzene­sulfonate

In the mol­ecular structure of the title compound, C15H11NO4S3, the 1,2,4-dithia­zolone and central benzene rings are approximately coplanar, making a dihedral angle of 3.08 (7)°. The central benzene ring and the 4-methyl­benzene ring subtend a dihedral angle of 57.47 (8)°. In the crystal, π–π stacking occurs between the central benzene ring and the 1,2,4-dithia­zolone ring of adjacent mol­ecules, which are aligned almost parallel, the centroid–centroid distance being 3.555 (7) A.
