The solubility in the CsH{sub 2}PO{sub 4}‒CsHSO{sub 4}‒H{sub 2}O system at different temperatures (25, 50, and 75°C) is studied and the phase equilibria in the Rb{sub 3}H(SO{sub 4}){sub 2}‒RbH{sub 2}PO{sub 4}‒H{sub 2}O system under isothermal conditions (at 25°C) are analyzed. The temperature and concentration conditions for forming Rb{sub 2}(HSO{sub 4})(H{sub 2}PO{sub 4}), Rb{sub 4}(HSO{sub 4}){sub 3}(H{sub 2}PO{sub 4}), Cs{sub 4}(HSO{sub 4}){sub 3}(H{sub 2}PO{sub 4}), Cs{sub 3}(HSO{sub 4}){sub 2}(H{sub 2}PO{sub 4}), Cs{sub 2}(HSO{sub 4})(H{sub 2}PO{sub 4}), and Cs{sub 6}H(HSO{sub 4}){sub 3}(H{sub 2}PO{sub 4}){sub 4} compounds (the latter has been obtained for the first time) are determined. The conditions for growing large single crystals of complex acid rubidium and cesium salts are found.
