The molecules of the title compound, C10H10O5, are linked by
O—H O hydrogen bonds into a linear chain along [201].
Comment
The crystal structures of 2- and 3-carboxyphenoxyacetic acid have been reported previously. The 2-isomer exists as a zigzag chain polymer hydrogen-bonded through a pair of hydrogen bonds (Byriel et al., 1991), whereas the 3-isomer exists as a monohydrate that displays a three-dimensional hydrogen-bonded network (Gu et al., 2004). The structure of the 4-isomer has not been reported to date, as the compound does not furnish single crystals. Interest in the 4-isomer is extended to the title compound, (I), which has an extra methylene linkage.
The title compound is anhydrous (Fig. 1). A pair of hydrogen bonds (Table 1) links adjacent molecules into a linear chain along [201] (Fig. 2).
Experimental
4-Carboxyphenoxyacetic acid was synthesized in a manner analogous to that used for synthesizing 3-carboxyphenoxyacetic acid (Guet al., 2004), but with 4-hydroxybenzoic acid in place of 3-hydroxybenzoic acid and 3-chloropropionic acid in place of chloroacetic acid. Colourless crystals of (I) separated from the aqueous solution after several days.

Carbon-bound H atoms were positioned geometrically, with C—H = 0.93 or 0.97 A˚ , and were included in the refinement in the riding-model approximation, withUiso(H) = 1.2Ueq(C). The acid H atoms were located in a difference Fourier map and were refined with a distance restraint of O—H = 0.82 (1) A˚ ; their displacement para-meters were freely refined.
