Notes:
Raman spectra were obtained for nine molten mixtures of SbCl3 and AlCl3, as well as for the pure components. Also three molten mixtures of AlCl3/NaCl/SbCl3 were studied. Molten AlCl3 contains molecular Al2Cl6(D2h) while molten SbCl3 contains pyramidal (C3v) molecules aligned head to tail. The Raman spectra showed the presence of Al2Cl6 molecules in molten SbCl3/AlCl3 mixtures containing 40 mol% or more AlCl3 but gave no evidence for the formation of SbCl2+ and AlCl4-. However, SbCl3 is structurally modified by the addition of AlCl3 as seen from the shift of the highest Sb—Cl stretching frequency. There is also spectral evidence that points to the formation of polymers that are different from those in pure SbCl3, and it cannot be ruled out that there may be a chloride-deficient antimony species in the AlCl3-rich mixtures. The molecular nature of the observed modifications in these mixtures cannot be deduced solely on the basis of the recorded spectra.
