Tetraethylammonium Tetrabromogallate III

The structures of the [Ga2X6]2- anions have been determined by X-ray crystallography.4-6 The vibrational spectra have also been reported 1 a characteristic Raman feature is the intense band due to in-phase stretching of Ga-X and 

The known compounds [R4N][GaX4], for which convenient preparative procedures are described here, were characterized by analysis for halogen, and by their infrared spectra, in which a strong Ga-X stretching band occurs at 378 cm 1 (X = Cl), 278 cm 1 (X = Br) or 222 cm 1 (X = I).
