3-Benzyl-2-phenyl-1,3-thia-zolidin-4-one.

In the title compound, C16H15NOS, the thia­zolidine ring, which is essentially planar [maximum deviation = 0.071 (2) A], makes dihedral angles of 88.01 (8) and 87.21 (8)° with the terminal phenyl rings. The dihedral angle between the phenyl rings is 49.45 (5)°. In the crystal, mol­ecules are linked by a weak inter­molecular C—H⋯O hydrogen bond, forming a supra­molecular chain along the b axis. Furthermore, the crystal packing is stabilized by a weak C—H⋯π inter­action.
