Abstract

$2K^+.C_6H_{11} O_9 P_{2-}. 5H_2O, M_r = 426.4$, monoclinic, $P2_1$, a=6"228 (1), b = 14.600(2), c = 8.982 (1) $\AA,\beta$ = 102.01 $(1)^0$, V= 798.4 $\AA^3$, Z= 2, $D_m$ = 1.756, $D_x = 1.773 Mg m^{-3}$, $\lambda(Cu K\alpha) = 1.5418 \AA, \mu = 7 mm^{-l}$, F(000) = 444, T= 293 K, R = 0.033, wR=0.035 for 1549 unique reflections with $I> 3\sigma(I)$. The ugar ring adopts a $^4C_1$ conformation. The conformation about the exocyclic C5-C6 bond is gauche-trans. The phosphate group exists as adianion with charges localized on 07 and 08 atoms. One of the metal ions binds to the phosphate group directly. All the hydroxyl O atoms, except O4-H, are involved in hydrogen bonding with the water O atoms
