Beryllium forms binary compounds with many non-metals.

All four anhydrous halides are known.

BeF2 has a silica-like structure with corner-shared BeF4 tetrahedra.r beryllium atoms coordinated to a central oxide ion.[21]
[edit]

BeCl2 and BeBr2 have chain structures with edge-shared tetrahedra.

They all have linear monomeric gas phase forms.

[20]
Beryllium oxide, BeO, is a white, high-melting-point solid, which has the wurtzite structure with a thermal conductivity as high as some metals. BeO is amphoteric.

Salts of beryllium can be produced by treating Be(OH)2 with acid.

[20]
Beryllium sulfide, selenide and telluride all have the zincblende structure.

[21]
Beryllium nitride, Be3N2 is a high-melting-point compound which is readily hydrolyzed.

Beryllium azide, BeN6 is known and beryllium phosphide, Be3P2 has a similar structure to Be3N2.

[21]
A number of beryllium borides are known, Be5B, Be4B, Be2B, BeB2, BeB6, BeB12.

[21]
Beryllium carbide, Be2C, is a high melting, brick red compound that reacts with water to give methane.

[21] No beryllium silicide has been identified.

Basic beryllium nitrate and basic beryllium acetate have similar tetrahedral structures with four beryllium atoms coordinated to a central oxide ion.
