Beryllium Acetylide

Beryllium Acetylide A70-R Beryllium Azide A524-R Beryllium Carbide.. See under Acetylides and Carbides A71-L Beryllium Diazide A524-R Binding Energy. See under Atomic Energy A500-R... 

A few simple beryllium acetylide structures are known. In one of these structures, illustrated as (112), the metal cation is symmetrically coordinated side-on to a triple bond. 

Why can calcium carbide be called an acetylide, while beryllium and aluminium carbides cannot be given this name ... 

These compounds have the characteristics of a salt, that is, they have a fixed composition their physical properties are unlike ftiose of their constituent elements they are generally transparent to optical radiation and are good electrical insulators. They form transparent and colorless crystals. Some contain ions such as aluminum carbide (AI4C3) and beryllium carbide (Be2C). They evolve methane when hydrolyzed and for that reason are usually known as methanides. Others contain ions such as calcium carbide (CaC2) they yield acetylene when hydrolyzed and are known as acetylides.1 1...
