Saturated aqueous solutions of lanthanide chlorides are studied by means of X-ray diffraction. Models of the investigated solutions are used to calculate quantitative characteristics of the immediate environment of ions in solutions using the obtained experimental data. It is established that all of the investigated systems are characterized by similar structures. Cations coordinate six solvent molecules in the first coordination sphere as the Ln3+–OH2 distances become shorter upon transitioning from light to heavy ions. Non-contact ion associates form in all the systems.
