✦ Synopsis

D-Gluconic

acid monohydrate. obtained in crystalline form by slow evaporation of an aqueous solution, is monoclinic, space group P2,. with a = 8.430(9), b = 5.403(6), c = l&406(9)

A, p = 96.88( 6)", and Z = 2. The crystal structure was determined from three-dimensional X-ray diffraction data taken on an automatic diffractometer with MoKa, and relined by least-squares techniques 10 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-gkonate.

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.
