The molecule is approximately planar in the solid state, and adjacent molecules are connected by C-H center dot center dot center dot O and C-H center dot center dot center dot pi(phenyl) interactions. In the C-H center dot center dot center dot pi interaction, the C center dot center dot center dot CgA distance is 3.916 (4) angstrom (CgA is the non-fused benzene ring centroid) and the C-H center dot center dot center dot pi angle is 156 (2)degrees. A feature of the molecular geometry is the narrow C-S-N angle of 92.51 (9)degrees in the five-membered ring. This angle relieves strain from the ring and makes it possible for the whole saccharin group to become quite planar.eninfo:eu-repo/semantics/closedAccessArticle61O243O24510.1107/S01082701050051602-s2.0-3074444007315805640N/AWOS:000228056500034N/A
