| Abstract: | CrCl3,g is chemically transported by means of Al2Cl6,g (～1 atm) in a temperature gradient (e. g. 500 → 400°C). Quantitative transport experiments have shown that the reaction goes via the gas molecule CrCl3 · 3 AlCl3. Its probable structural formula is CrCl6/2(AlCl2/2Cl2)3, containing Cr3+ in an octahedral and Al3+ in a tetrahedral Cl coordination1). |
