Not to be confused with beryllium nitride, Be3N2.

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

Synthesis

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

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