Abstract

Primary data of the X-ray diffraction experiment on DyBr3 and YbBr3 aqueous solutions in salt:water molar ratios of 1:20 are presented. The occurrence of a pre-main peak in the curves of normalized scattering intensities determines the average distance between cations in these solutions, and hence, directs to a model description of the structure of solutions. Based on the determination of boundaries of the cation complex and taking into account the deficit of solvent, a model of the cation complex is supposed to consist of two coordination shells involving at least two anions.
