Synthesis and Crystal Structure of Phosphorus Vandium Heteropolyacid Sodium
Abstract:
phosphorus vandium heteropolyacid sodium, H78N12NaO116P2V30, is prepared by the hydrothermal method. Cubic, Fm-3m. a =b = c = 20.022(2) Å α=β=γ= 90. V=10680.0(17) Å3. Z=4. R1 =0.0388, wR2 =0.1200. T=298(2) K. The V atoms are linked with O atom bridge. The molecular structure is stabilized by the O-H...O and O-H...N intermolecular and intramolecular hydrogen-bond interaction.
