AbstractAbstract

[en] Cocrystallization of Cf²⁺, Es²⁺, Tm²⁺ and divalent lanthanides (Yb, Eu, Sm) with SrI₂x18 crown-6 in THF medium with Tm²⁺ oxidation potential has been studied. All investigated elements are shown to cocrystalize with a solid phase due to formation of actual solid solutions. Values of their cocrystallization coefficients are close to 1 and don't depend on concentration of ion iodide. The conclusion is made that in THF solutions actinide diiodides as well as lanthanide diiodides and SrI₂ are dissociated completely
