Abstract
The crystal structure of optically active 2-(4-chlorophenoxy)propionic acid (C 9 H 9 ClO 3 ) has been determined. The carboxylic acid group is in an antiplanar conformation and hydrogen bonds along the twofold screw axis link the carboxylic acid groups to form a catemer motif, in contrast to the hydrogen-bonded cyclic dimers observed in the equivalent racemic compound. Also, the weaker intermolecular interactions display significant differences.
