Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2 O) 6 ]Cl 3 , containing six water molecules of hydration .
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Tetrachloroaluminate [AlCl 4] − is an anion formed from aluminium and chlorine.The anion has a tetrahedral shape and is isoelectronic with silicon tetrachloride.Some tetrachloroaluminates are soluble in organic solvents, creating an ionic non-aqueous solution, making them suitable as component of electrolytes for batteries.
Two common modes of Lewis acid catalysis in reactions with polar mechanisms. In reactions with polar mechanisms, Lewis acid catalysis often involves binding of the catalyst to Lewis basic heteroatoms and withdrawing electron density, which in turn facilitates heterolytic bond cleavage (in the case of Friedel-Crafts reaction) or directly activates the substrate toward nucleophilic attack (in ...
Nitronium tetraperchloratoaluminate is made from exact amounts of nitronium perchlorate and anhydrous aluminium chloride combined in liquid sulfur dioxide. [1]Ammonium tetraperchloratoaluminate can be formed by three moles of nitronium perchlorate, one mole of anhydrous aluminium chloride, and one mole of ammonium perchlorate combined in liquid sulfur dioxide.
The aluminium halides are: Aluminium bromide; Aluminium chloride; Aluminium fluoride; Aluminium iodide; Aluminium monobromide; Aluminium monochloride; Aluminium monofluoride; Aluminium monoiodide; Ions also exist aluminium tetrafluoride AlF − 4

As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite, with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual ...
