Beryllium azide, {{chem2|Be(N3)2}}, is an inorganic compound. It is the beryllium analog of hydrazoic acid ({{chem2|HN3}}).
Synthesis
Beryllium azide has been synthesised by the reaction of beryllium chloride with neat trimethylsilyl azide:{{ cite journal | journal = Main Group Metal Chemistry | year = 1999 | volume = 22 | issue = 6 | pages = 357–360 | title = Synthesis and spectroscopic characterization of beryllium azide and two derivatives | first1 = T.

:{{chem2|BeCl2 + 2 Me3SiN3 → Be(N3)2 + 2 Me3SiCl}}
Alternatively, dimethylberyllium reacts with hydrazoic acid in dry diethyl ether at −116 °C:
:{{chem2|Be(CH3)2 + 2 HN3 → Be(N3)2 + 2 CH4}}
Structure
Infrared and Raman spectra suggest that beryllium azide consists of infinite chains, with tetrahedrally coordinated beryllium(II) atoms covalently bridged by one end of the azide units.
