Phase behavior, crystal structure, and superprotonic conductivity of Cs[(H <sub>2</sub> PO <sub>4</sub> ) <sub> 1−2 <i>y</i> </sub> (HPO <sub>4</sub> ) <sub> <i>y</i> </sub> ]: phosphate deficient analogs to cubic CsH <sub>2</sub> PO <sub>4</sub> in
Cubic CsH 2 PO 4 , which crystallizes in the CsCl structure-type, can support a large concentration of excess Cs via phosphate vacancies. Dissolution of Cs 3 PO 4 into the cubic structure lowers the temperature at which superprotonic conductivity occurs.
