Solutions of Gallium Trichloride in Ethers: A 71 Ga NMR Study and the X-Ray Structure of GaCl3 · Monoglyme

Abstract

Solutions of GaCl3 in various ethers have been studied by 71Ga NMR spectroscopy. δ7lGa data indicate that the predominant species in diethylether and tetrahydrofuran solutions are GaCl3 · O(C2H5)2-, and GaCl3-2OC2H8, 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. © 1990, Walter de Gruyter.
