(4S)-4-[(R)-Chloro-(4-nitro-phen-yl)meth-yl]-1,3-oxazolidin-2-one.

ABSTRACT: 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?? inter-actions [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 inter-actions. The absolute configuration of the two stereogenic centres was determined using the anomalous dispersion of the Cl atom.
