AbstractA new compound from the tellurate family was synthesized under a slow evaporation conditions. A crystalline sample of Cs2(HAsO4)0.32(SO4)0.68·Te(OH)6 (CsAsSTe) was calorimetric and spectroscopically characterized. The infrared and Raman spectra of this new compound recorded at room temperature, in the frequency range 500–4,500 and 50–1,500 cm−1, respectively, confirm the presence and the independence of two types of anion HAs/SO4 and TeO6. The thermal analysis of the title compound shows one endothermal and intense peak at 512 K accompanied by a shoulder at 506 K. However, the conductivity evolution versus temperature showed the presence of the protonic super conduction phase transition. The conductivity relaxation parameters of some H+ and Cs+ conducting in the CsAsSTe material have been determined from an analysis of ac conductivity data measured in a wide temperature range. Transport properties in this compound appear due to H+ ions hopping mechanism.
