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.
Beryllium difluoride is different from the other difluorides. In general, beryllium has a tendency to bond covalently , much more so than the other alkaline earths and its fluoride is partially covalent (although still more ionic than its other halides).
The exception is beryllium difluoride. In addition, many transition metal difluorides are water-soluble. Calcium difluoride is a notable compound.

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°.
Molecules of theoretical curiosity such as neon difluoride (NeF 2) and beryllium dilithide (BeLi 2) represent examples of inverted electronegativity. [13] As a result of unusual bonding situation, the donor lone pair ends up with significant electron density on the central atom, while the acceptor is the "out-of-phase" combination of the p ...
The Be–F bond length is between 145 and 153 pm.The beryllium is sp 3 hybridized, leading to a longer bond than in BeF 2, where beryllium is sp hybridized. [11] In trifluoroberyllates, there are actually BeF 4 tetrahedra arranged in a triangle, so that three fluorine atoms are shared on two tetrahedra each, resulting in a formula of Be 3 F 9.
