Solutions of GaCl3 in various ethers have been studied by 71Ga NMR spectroscopy. σ71Ga data indicate that the predominant species in diethylether and tetrahydrofuran solutions are GaCl3 · O(C2H5)2 and GaCl3. 2OC4H8, respectively. However, in monoglyme solution dissociation occurs and the product crystallizing from the solution is [cis-GaCl2(monoglyme)2]GaCl4 as demonstrated by an X-ray structure determination of the solvate GaCl3 · monoglyme.
