Abstract
Aqueous solutions of dysprosium chloride in a wide concentration range are studied by X-ray diffraction analysis under standard conditions. The scattered X-ray radiation intensity curves are characterized by prepeaks at low values of the wave vector. Their interpretation and an analysis of changes at different concentrations are performed. The structure of concentrated solutions is formed due to interionic interactions of different types. On the contrary, dilute solutions are characterized by the determining role of the quasi-tetrahedral structure of the solvent. The prepeaks are also observed on the intensity curves of dilute solutions, indicating that these solutions retain the “long-range” ordering.
