The phase equilibria in the quaternary water–salt system Cs2SO4–Rb2SO4–H2SO4–H2O have been studied. The crystallization ranges are determined, and single crystals of (Cs1 – xRbx)2SO4 and Cs1 – xRbxHSO4 solid solutions have been grown. The (Cs1 – xRbx)3H(SO4)2 and (Cs1 – xRbx)5H3(SO4)4 · yH2O compounds are obtained for the first time.



This work was supported by the Ministry of Science and Higher Education within the State assignment FSRC «Crystallography and Photonics» RAS in part of characterization of the physicochemical properties of crystals, the Council on Grants at the President of the Russian Federation (project no. MK-3403.2017.3) in part of study of the phase equilibria in the Cs2SO4–Rb2SO4–H2SO4–H2O system. The physicochemical characterization of crystals was supported by the Federal Agency for Scientific Organizations (contract no. 007-ГЗ/Ч3363/26). This study was carried out using equipment of the Shared Research Center of the Institute of Crystallography, Russian Academy of Sciences (the Ministry of Education and Science of the Russian Federation, project no. RFMEFI62114X0005).
