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

Abstract

The central 1,3-oxazolidine-2-thione ring in the title compound, C17H15NO3S, is approximately planar with maximum deviations of 0.036 (4) and -0.041 (5) angstrom for the O and methylene-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)degrees. 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)degrees. the dihedral angle formed by the benzene rings is 62.8 (2)degrees 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 center dot center dot center dot O, C-H center dot center dot center dot S and C-H center dot center dot center dot pi interactions.
