Abstract
Abstract d -Gluconic acid monohydrate, obtained in crystalline form by slow evaporation of an aqueous solution, is monoclinic, space group P2 1 , with a = 8.430(9), b = 5.403(6), c = 10.406(9) A, β = 96.88(6)°, and Z = 2. The crystal structure was determined from three-dimensional X-ray diffraction data taken on an automatic diffractometer with MoKα, and refined by least-squares techniques to R = 0.045 for 1018 reflexions. The molecules of d -gluconic acid exist in a bent-chain conformation similar to that found in ammonium d -gluconate. All of the oxygen atoms participate in intermolecular hydrogen bonds utilising all oxygen-bonded hydrogen atoms, and the water molecule connects four different acid molecules.
