(4S)-4-[(R)-Chloro­(4-nitro­phen­yl)meth­yl]-1,3-oxazolidin-2-one

In the title compound, C₁₀H₉ClN₂O₄, the oxazolidinone ring adopts a near-planar conformation, with mean and maximum deviations of 0.0204 (8) and 0.0328 (8) Å, respectively. The nitro group is twisted slightly from the plane of the benzene ring, making a dihedral angle of 6.79 (3)°. The dihedral angle between the mean oxazolidinone plane and the benzene ring is 56.21 (3)°. In the crystal, N—H...O hydrogen bonds and N—O...π inter­actions [O...centroid distances = 3.478 (1) and 3.238 (1) Å] dominate the packing, forming infinite zigzag chains along the b-axis direction. Neighbouring chains are linked together through C—H...O and C—H...Cl inter­actions. The absolute configuration of the two stereogenic centres was determined using the anomalous dispersion of the Cl atom.
