• Canonical SMILES: [Be+2].[F-].[F-]
• Description: Beryllium fluoride has the formula, BeF2, and is a hygroscopic, amorphous solid with a melting point of 800°C. It is soluble in water and is used in beryllium metallurgy in which the metal, Be, is employed as an alloy. Solid crystalline BeF2 has a silica-like structure with beryllium in a four-coordinate position.
• Physical properties: Glassy solid; tetragonal crystal system; hygroscopic; density 2.1 g/cm3; melts BERYLLIUM FLUORIDE 101 at 552°C; vaporizes at 1,169°C; very soluble in water; sparingly soluble in alcohol.
• Uses: manufacture of Be and Be alloys; manufacture of glass; in nuclear reactors. Beryllium fluoride is used in biochemistry, particularly protein crystallography, since it binds in some of the same ways as phosphate does in human tissues. ADP and beryllium fluoride together tend to bind to ATP sites and inhibit protein action, making it possible to crystallize proteins in the bound state. Beryllium fluoride forms a basic constituent of the preferred fluoride salt mixture used in liquid-fluoride nuclear reactors. Typically, beryllium fluoride is mixed with LiF to form a base solvent, into which fluorides of uranium and thorium are introduced. Beryllium fluoride is exceptionally chemically stable and LiF/BeF2 mixtures have low melting points and the best neutronic properties of any of the fluoride salt combinations appropriate for reactor use. Beryllium fluoride (BeF2) is an example of beryllium that has an oxidation state of +2, combining with a negative anion element with an oxidation state of –1. Beryllium fluoride is also used along with magnesium metal in the chemical reduction process to produce beryllium metal.
