(R)-2-Phenoxy-1-(4-phenyl-2-sulfan-ylidene-1,3-oxazolidin-3-yl)ethanone

Abstract

The central 1,3-oxazolidine-2-thione ring in the title compound, C 17H 15NO 3S, is approximately planar with maximum deviations of 0.036 (4) and -0.041 (5) Å for the O and methyl-ene-C atoms, respectively. The dihedral angles formed between this plane and the two benzene rings, which lie to the same side of the central plane, are 86.5 (2) [ring-bound benzene] and 50.6 (3)°. The ethan-1-one residue is also twisted out of the central plane, forming a O-C-N-C torsion angle of 151.5 (5)°. The dihedral angle formed by the benzene rings is 62.8 (2)° so that overall, the molecule has a twisted U-shape. In the crystal, molecules are linked into supramolecular arrays two molecules thick in the bc plane through C-H⋯O, C-H⋯S and C-H⋯π interactions.
