AB  - On the basis of previously recorded Raman and IR spectral data on different crystallohydrates of alkaline-earth 12-tungstophosphoric acid salts (obtained from mother solution and those kept under constant relative humidity (RH) of 35%), an effort was made to determine the position of cations in the Keggin unit. Shifts or band splitting in vibrational spectra of the salts, as well as the changes in band intensities were found to be connected to the cation properties. The spectral data also demonstrated a great influence of cation properties on the secondary structure of Keggin anions and dynamics of protonic species.

AB  - This contribution presents the results of the investigation of Mg2+ and Ca2+ 12-tungstophosphoric acid (WPA) salts as superionic proton conductors. We have identified protonic species as charge carriers in several hydration degrees of these salts by IR spectroscopy at low, room and high temperatures. In the IR spectra we have found the characteristic frequencies for H3O+, OH-, H2O, H5O2+. Also, we have investigated the dynamic equilibrium between protonic entities in the function of temperature, as well as the nature and the strength of hydrogen bonds in those compounds. During the process of calcination, these salts undergo a few phase transformations. The temperatures of interest for the further investigations were taken from data of thermal analysis.
