“…With an accessible melting point of 77.9 °C, GaCl 3 has properties that exist between ionic liquids and molten salts, making it an unconventional solvent to investigate oxidative chemical transformations. Reports have detailed investigations of GaCl 3 as a solvent matrix for chalcogen oxidative dissolution 25,26 and as a Lewis acidic solvent for the dissolution of the elements bismuth 27−29 and antimony. 30 Our prior work demonstrated the potential of GaCl 3 as a chlorine-transfer reagent for uranium and plutonium, 31 furthering our interests in exploring GaCl 3 as a solvent in metal dissolution chemistry.…”

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 C6H5F to [Ga]+ was observed. All complexes were characterized through elemental analysis (F and Cl), IR and UV–vis–near-IR spectroscopies, and both solution and solid-state NMR techniques.
