Al2F6 is the chemical formula for aluminum fluoride, a white solid that is commonly used as a catalyst in organic synthesis reactions and as an additive in the production of aluminum metal. It has a melting point of 1291°C and is insoluble in water.
The formula for dialuminum hexafluoride is Al2F6. It consists of two aluminum atoms bonded to six fluorine atoms.
The higher boiling point of aluminum trifluoride compared to silicon tetrafluoride is due to the stronger intermolecular forces present in aluminum trifluoride. The aluminum atom can form stronger dipole-dipole interactions and van der Waals forces with neighboring molecules, leading to a higher boiling point. In contrast, silicon tetrafluoride exists as a gas due to its weaker intermolecular forces of attraction, resulting in a lower boiling point.
