(5S)-5-Methyl-3-phenyl-2-sulfanyl-idene-1,3-thia-zolidin-4-one

rac-cis-5-Methyl-2,3-diphenyl-1,3-thiazolidin-4-one

In the racemic title compound, C16H15NOS, the thiazolidine ring adopts an envelope conformation, with the S atom as the flap. The dihedral angles between the heterocycle (all atoms) and pendant C– and N-bound benzene rings are 69.75 (14) and 56.56 (11)°, respectively; the aromatic rings are almost orthogonal to each other, with a dihedral angle of 76.04 (14)° between them. In the crystal, molecules are linked by weak C—H...O hydrogen bonds to generate [101] chains, with alternating molecules being enantiomers. A weak C—H...π interaction is also observed.
