2,3-Diphenyl-2,3,5,6-tetra-hydro-4H-1,3-thia-zin-4-one.
The six-membered thia-zine ring in the title compound, C16H15NOS, adopts a half-chair conformation, with the S atom forming the back of the chair. The base of the chair has a slight twist reflected in the r.m.s. deviation (0.0756 Å) of those five atoms from the plane defined by them. The phenyl substituents are almost perpendicular to each other [dihedral angle 87.06 (9)°]. In the crystal, mol-ecules are linked into chains parallel to the c axis through C-H⋯O inter-actions.
