➢ Aluminum Chloride
- Aluminum chloride has a chemical formula of AlCl3 and is a compound of chlorine and aluminum .
Aluminum chloride has a very low melting point and boiling point, and it will sublimate and is a covalent compound. Molten aluminum chloride is not easily conductive, unlike most halogen- containing salts (such as sodium chloride ).
AlCl3 adopts the “YCl3” structure, which is the most densely packed layered structure of Al3+ cubic, while Al3+ in AlBr3 accounts for the gap between adjacent tetrahedrons of the most densely packed frame of Br − .
When melted, AlCl3 forms a volatile dimer, Al2Cl6. At higher temperatures, the Al2Cl6 dimer dissociates to form a planar triangle AlCl3 , and trifluoride Boron (BF3 ) has a similar structure.
- Aluminum chloride is colorless transparent crystal or white and slightly yellowish crystalline powder.
When the vapor of aluminum chloride is dissolved in a non-polar solvent or in a molten state , it exists in the form of a covalent dimer molecule (Al2Cl6 ). Soluble in water and many organic solvents. The aqueous solution is acidic. In the presence of aromatic hydrocarbons, aluminum chloride mixed with aluminum can be used to synthesize bis (aromatic hydrocarbon) metal complexes.
For example
- Diphenyl chromium is prepared by Fischer-Hafner synthesis of specific metal halide.
