Notes:
Raman spectra of both polycrystalline samples and single crystals of CsAlCl4 and RbAlCl4 (space group Pnma (D2h16)) have been recorded in the temperature range 298-80 K.As for the other chloroaluminates, we find the four characteristic bands of the tetrahedral AlCl4- anion at 353, 128, 485-503, 180-187 cm-1 and 356, 127, 486-505 and 180-187 cm-1, respectively, for the salts CsAlCl4 and RbAlCl4. The Raman spectra of single crystals of these two compounds are similar and show that these two salts are isostructural. An assignment of the observed bands is proposed. The results are compared with those for the polyatomic cation (nitrosyl and ammonium) tetrachloroaluminates.
