(5Z)-3-(2-Oxopropyl)-5-(3,4,5-trimethoxybenzylidene)-1,3-thiazolidine-2,4-dione

Abstract

In the crystal of the title molecule, C16H17NO6S, there are three sets of intermolecular C—H...O hydrogen bonds, as well as two sets of intermolecular C—H...π(ring) interactions. In addition, the thiazolidene rings participate in offset π–π stacking interactions [centroid–centroid distance = 3.685 (1) Å]. These generate small channels running parallel to the a axis with approximate cross-sections of 3.7 × 8.1 Å.
