3-Butyl-2-phenyl-1,3-thiazolidine-1,4-dione

In the title compound, C13H17NO2S, the thiazolidine-1,4-dione ring adopts an envelope conformation with the S atom lying 0.631 (4) Å out of the plane formed by the other four ring atoms; the phenyl ring is almost perpendicular [88.74 (8)°] with respect to the ring C—C—N—C atoms and the butyl chain is in a fully extended conformation. In the crystal, a supramolecular two-dimensional arrangement arises from weak intermolecular C—H...O interactions
