N-Saccharinylmethyl ether

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 R42(10).
