Abstract

Gallium(III) halides react with cerium(III), ytterbium(III), or dysprosium(III) halides in the presence of alkylated benzenes yielding mononuclear complexes of the general formula [Ln(η6-arene)(GaX4)3]. The X-ray structures of [Ce(C6H5Me)(GaCl4)3] (1), [Ce(p-C6H4Me2)(GaCl4)3]·0.5(p-C6H4Me2) (2), [Yb(C6H5Me)(GaCl4)3] (3), [Yb(p-C6H4Me2)(GaCl4)3]·0.5(p-C6H4Me2) (4), and [Dy(C6H5Me)(GaBr4)3] (5) were determined. Arene ligands in the cerium–toluene compound 1 can be substituted by polycyclic aromatic hydrocarbons (PAHs); the compounds [Ce(naphthalene)(GaCl4)3] (6) and [Ce(pyrene)(GaCl4)3]·0.5(pyrene) (7) have been isolated and structurally characterized.
