2-(2-Oxothiolan-3-yl)isoindoline-1,3-dione

Abstract

In the title compound, C12H9NO3S, the isoindoline-1,3-dione group is almost planar, with an r.m.s. deviation of 0.020 Å, whereas the heterocyclic ring approximates to an envelope with the methylene group not adjacent to the S atom in the flap position. A short intramolecular C—H...O contact generates an S(6) ring motif. In the crystal structure, weak aromatic π–π stacking interactions occur between the centroids of the benzene rings at a distance of 3.558 (2) Å.
