Measurements have been made on the cocrystallization of Cf/sup 2 +/, Es/sup 2 +/, Fm/sup 2 +/ and the divalent lanthanoids with SrI/sub 2/ x 18-crown-6 in THF at the oxidation potential of Tm/sup 2 +/. All these elements cocrystallize with the solid because of the formation of true solid solutions. The cocrystallization coefficients are close to one and are independent of 1/(I/sup -/). It is concluded that the actinoid diiodides resemble SrI/sub 2/ and the lanthanoid diiodes in being completely dissociated in solution in THF.
