Notes:
The Raman spectra of NbCl5 dissolved in AlCl3-NaCl and AlCl3-KCl melten and molten Al2Cl6 have been examined as a function of melt composition, temperature, and NbCl5 concentration. The results are compared with previously published data. The binary AlCl3-NbCl5 system at ∼200°C contains noninteracting NbCl5, Nb2Cl10 and Al2Cl6 molecules. The complexes formed when NbCl5 is dissolved in AlCl3-MCl (M=Na and K) melts depend on acidity and temperature: NbCl6- is present only in very basic melts; NbCl5 is stable in basic and acidic melts; Nb2Cl10 is found only in acidic melts. High temperature favors formation of NbCl5 while low temperature stabilizes Nb2Cl10.
