Abstract
In the title molecule [systematic name: 1,1,1′,1′-tetraoxo-2,2′-(oxydimethylene)bi(1,2-benzothiazol-3-one)], C16H12N2O7S2, the benzisothiazole ring systems are individually planar [maximum deviations of 0.0497 (13) and 0.0195 (19) Å] and their mean planes are inclined at a dihedral angle of 62.76 (4)°. The crystal structure is stabilized by weak intermolecular C—H⋯O interactions. Two O atoms bonded to two S atoms and four aryl H atoms belonging to two symmetry-related molecules lying about an inversion center form a hydrogen-bonded 10-membered ring with graph-set notation R 4 2(10).

Two O atoms bonded to two S atoms and four aryl H atoms belonging to two symmetry-related molecules lying about an inversion center form a hydrogenbonded 10-membered ring with graph-set notation R24(10)
Continuing our investigations in the synthesis and development of new saccharin derivatives (Ahmad et al, 2010; Siddiqui et al, 2010) with medicinal potentials, we report the crystal structure of a novel compound in this paper
The bond distances and angles in the title molecule agree well with the cortresponding bond distances and angles reported in closely related compounds (Ahmad et al, 2009; Gul et al, 2010; Khalid et al, 2010; Siddiqui et al, 2007; 2008)
Summary
Two O atoms bonded to two S atoms and four aryl H atoms belonging to two symmetry-related molecules lying about an inversion center form a hydrogenbonded 10-membered ring with graph-set notation R24(10)
