چکیده
The central 1,3-oxazolidine-2-thione ring in the title compound, C(17)H(15)NO(3)S, 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 mol-ecule has a twisted U-shape. In the crystal, mol-ecules are linked into supra-molecular arrays two mol-ecules thick in the bc plane through C-H⋯O, C-H⋯S and C-H⋯π inter-actions.

In the title mol-ecule, C(11)H(11)Cl(2)NO(2), the oxazolidine ring is in an envelope conformation with the O atom forming the flap; the other four essentially planar ring atoms (r.m.s. deviation = 0.012 Å) form a dihedral angle of 91.1 (3)° with the phenyl ring. In the crystal structure, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming one-dimensional chains.
