Beryllium fluoride has distinctive optical properties. In the form of fluoroberyllate glass, it has the lowest refractive index for a solid at room temperature of 1.275. Its dispersive power is the lowest for a solid at 0.0093, and the nonlinear coefficient is also the lowest at 2 × 10 −14.
Structure of beryllium fluoride (BeF 2), a compound with a linear geometry at the beryllium atom.. The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°.
Structure of "diphenyl beryllium, which has the formula Be 3 (C 6 H 5) 6. [1]Organoberyllium chemistry involves the synthesis and properties of organometallic compounds featuring the group 2 alkaline earth metal beryllium (Be). [2]
Tetrafluoroberyllate or orthofluoroberyllate is an anion with the chemical formula [Be F 4] 2−.It contains beryllium and fluorine.This fluoroanion has a tetrahedral shape, with the four fluorine atoms surrounding a central beryllium atom.
The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak bonding between the two fluorine atoms. [9] This is a result of the relatively large electron and internuclear repulsions, combined with a relatively small overlap of bonding orbitals arising ...

Adapting (re-captioning) an image of silica would be an excellent alternative: The literature describes SiO2 as a close structural analogue of BeF2, as already discussed in the article. I have also removed the statement that "BeF 2 is considered to be highly covalent"; surprisingly, it isn't (as discussed in a paper I read a few days ago).
Few foods are more appetizing to people than a juicy steak. Grilled to order and garnished with herbs like basil and chives, sauces such as au jus, peppercorn and A1, or vegetables like grilled ...
