Abstract
The asymmetric unit of the title compound, C9H10O6·H2O, consists of one 3-carboxyphenoxyacetic acid (3-CPOAH2) and one water molecule. The intermolecular interactions link symmetry-related molecules into hydrogen-bonded dimers. A supramolecular hydrogen-bonding network structure is formed via further intermolecular hydrogen bonds involving the water molecule.
