Structure of ammonium D-gluconate

X-ray powder diffraction data for ammonium D-gluconate, C6H11O7−NH4+

“…All of the reflections were indexed successfully using the CHEKCELL program (Laugier and Bochu, 2003). The lattice parameters were determined using the same program and the refined parameters are a =6.8059 (2) Å, b =7.6275 (2) Å, and c =17.8028 (5) Å, which compare well with the values published by Lis (1981).…”

“…Recent studies also indicated that salts of gluconic acid have properties that make it usable in other applications (Labuschagné et al , 2000; Labuschagné et al , 2001). The crystal structure of ammonium D -gluconate has been described by Lis (1981) (see Table I) and the structure shown in Figure 1. This paper is dedicated to the characterization of ammonium D -gluconate using X-ray powder diffraction.…”

Effects of Cation Interactions on Sugar Anion Conformation in Complexes of Lactobionate and Gluconate with Calcium, Sodium or Potassium

“…As a part of an extensive study of the influence of the cation on the conformation of the lactobionate or gluconate anions in carbohydrate-cation complexes (Lis, 1981(Lis, , 1984Jeffrey & Fasiska, 1972;Panagiotopoulos, Jeffrey, La Placa & Hamilton, 1974;Cook & Bugg, 1973), we have determined the crystal and molecular structures of the tetrahydrated calcium chloride salt of lactobionic acid, (1), potassium lactobionate, (2), sodium lactobionate monohydrate, (3), and calcium galactonate hydrate, (4). They are of the type of carbohydrate complex in which interactions between the cation and the carbohydrate anion play an important role structures containing a lactobionate or a galactonate anion have been available only for the bromide analogue of (1) (Cook & Bugg, 1973 The asymmetric part of the unit cell of (1) comprises one lactobionate and one C1-anion, one Ca 2÷ cation and four water molecules.…”
