The chemistry of gallium—IX. Laser Raman spectra of some gallium (III) halide complexes

Several new complexes of gallium (III) containing tetrachloro-, tetrabromo-, trichlorobromo- and tribromochlorogallate anions were prepared and their laser Raman spectra studied. The number and frequencies of the ν (gallium-halogen) vibrations are consistent with monomeric structures for the complexes prepared and showed T _d symmetry for GaCl ₄^- and GaBr ₄^- complexes and C^3ν symmetry for GaCl ₃Br ^- and GaBr ₃Cl ^- complexes.
