Abstract
The crystal structures have been determined for racemic and two optically active samples of 3-(2'-chloro-2'-phenylethyl)-2-thiazolidiniminium p-toluenesulfonate (C 11 H 14 ClN 2 S + .C 7 H 7 O 3 S - ) from low-temperature (122 K) X-ray diffraction data. The three crystal structures are virtually identical. The racemate crystallizes in the space group P2 1 /n, Z=4, with unit-cell dimensions a=8.5016 (10), b=8.2803 (11), c=27.447 (3) A and β=96.478 (9) o . The cation displays disorder of the Cl atom and the C atom to which it is bonded. The disorder can be rationalized in terms of the presence of two partially populated enantiomers with different conformations
