Abstract: The crystal structure of the title compound, K⁺·C₃H₄NO₄^-·H₂O, consists of potassium cations, monoanions of 2-carboxyacetohydroxamic acid [namely 2-(N-hydroxycarbamoyl)acetate] and solvent water molecules. The elements of the structure are united in a three-dimensional network by numerous KO coordinate bonds and O-HO and N-HO hydrogen bonds. The coordination sphere of the K⁺ ions may be described as a distorted double capped octahedron. Bond lengths and angles are similar to those in related compounds.
