Abstract
[ $LiK_{1-x}Rb_{x}SO_{4}(x=0.1,\;0.2)$ ] crystals were grown by means of aqueous solution growth technique at 313 K. Structure analysis of them was carried out with space group $P6_{3}(#173)$ by X-ray diffraction. In these compounds, the Li and $SO_{4}^{2-}$ ions lying on the three-fold axes formed infinite three-dimensional network and K and Rb atoms located on the six-fold axes are coordinated by twelve and fifteen O atoms respectively. The most suitable stabilization was achieved when the occupancy factors of K and Rb atoms are (0.91 : 0.09), (0.77 : 0.23) respectively.
