Abstract: Molecules of the title compound [systematic name: (2R,5S,7S)-2-phenyl-7-phenylsulfanyl-1-aza-3-oxabicyclo[3.3.0]octan-8-one], C₁₈H₁₇NO₂S, form high quality crystals even though they are only packed using C-HO(carbonyl) and weak C-HS interactions. The dihedral angle between the aromatic rings is 85.53 (5)°. The fused rings adopt envelope and twist conformations.
