Coordination complex of Na+ and alpha-D-glucose.
The structure of alpha-D-glucose-NaCl is presented. C6H12O6.1/2(NaCl).0.39(H2O), Mr = 216.40, trigonal, P3(1)21, a = b = 9.721 (3), c = 17.06 (1) A, V = 1396 (1) A3, Dm = 1.54 (1), Dx = 1.54 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 2.859 cm-1, F(000) = 683.4, T = 293 K, final R = 0.044 for 744 reflections with I greater than or equal to 3 sigma (I). The Na+ residues on a crystallographic twofold axis and is coordinated by six hydroxyls originating from four separate glucose molecules. The chloride ion is not involved in direct ionic interactions with the sodium ion.
