GdCl 3–H 2 O at 25° C are studied via saturation technique. Solubility diagrams are found to
be of a simple eutonic type and are characterized by the salting-out of chloride upon adding
fullerenol-d, and short branches of LaCl 3· 7H 2 O and GdCl 3· 6H 2 O crystallization, where
the salting-in effect is observed.
