AB  - Some structural properties of a magnesium salt of 12-tungstophosphoric acid, MgHPW12O40.nH(2)O (MgHVvTA-n), are reported. The influence of the Mg2+ ion on the structure, dynamics of the protonic species, and dielectric and conductive characteristics of the salt have been studied. The interaction of protonic species with Keggin anion was discussed. Preliminary results of the crystal structure indicate that the structure is composed of Keggin anions and Mg(OH2)(6) aqua-complexes. Some comparisons are made with other alkaline-earth and alkaline salts of WPA. The results of thermal analysis (TGA and DTA), X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), conductivity and permittivity measurements of MgHWPA-n are reported and discussed.

AB  - Heteropoly acids arc well known as supcrionic protonic conductors at room temperature. The conductivity depends upon the temperature and relative humidity of the surrounding. Recent results show that the conductivity is very much affected by monovalent exchange counter-ions. In this work the effect of monovalent ions (Li + , Na + , K + and Cs + ) on the nature and structure of hydrogen bonds, the presence of different protonic species as charge carriers, and the dynamic equilibrium of proton species as a function of temperature and ion characteristics were investigated.
