Beryllium azide, Be(N3)2, is an inorganic compound.

Synthesis[edit]

Beryllium azide has been synthesised by the reaction of beryllium chloride with neat trimethylsilyl azide:[2]

BeCl2 + 2Me3SiN3 → Be(N3)2 + 2Me3SiCl

Alternatively, dimethylberyllium reacts with hydrazoic acid in dry diethyl ether at −116 °C:[1]

Be(CH3)2 + 2HN3 → Be(N3)2 + 2CH4

Structure[edit]

Beryllium azide is predicted to consist of infinite chains, with tetrahedrally coordinated Be2+ ions linked by end-on bridging N3 ions.[2]
