Oxidative Dissolution of Lanthanide Metals Ce and Ho in Molten GaCl₃.

ABSTRACT: Gallium trichloride (GaCl₃) was used as a solvent for the oxidative dissolution of the lanthanide (Ln) metals cerium (Ce) and holmium (Ho). Reactions were performed at temperatures above 100 °C in sealed vessels to maintain the liquid phase for GaCl₃ during the oxidizing reactions. The best results were obtained from reactions using 8 equiv of GaCl₃ to metal where the inorganic complexes [Ga][Ln(GaCl₄)₄] [Ln = Ce (1), Ho (2)] could be isolated. Recrystallization of 1 and 2 employing fluorobenzene (C₆H₅F) produced [Ga(η⁶-C₆H₅F)₂][Ln(GaCl₄)₄] [Ln = Ce (3), Ho (4)] where reversible η⁶ coordination of
