N2  - The crystal structure of (±)-2-[4-(4-chlorophenoxymethyl)phenoxy]propionic acid has been determined by direct methods using three-dimensional X-ray diffraction data. The crystals are triclinic, P1, Z 2, a 9.345(2), b 12,602(2), c 6.741(1) Å, &#945; 101.37(1), &#946; 97.42(1), &#947; 101.75(1)º. The structure refined to give a final R 0.084 for 2172 observed reflections. The acid molecules form centrosymmetric hydrogen bonded cyclic dimers [O. . .O,2.619(4) Å] about a centre of symmetry in the cell. The oxopropionic acid side chain has a synplanar-synplanar (carbonyl) conformation while the planar p-chlorophenoxymethyl substituent in the p-position has a synclinal orientation relative to the primary phenoxy residue.
