Beryllium azide, , is an inorganic compound. It is a beryllium salt of hydrazoic acid . Synthesis Beryllium azide has been synthesised by the reaction of beryllium chloride with neat trimethylsilyl azide: Alternatively, dimethylberyllium reacts with hydrazoic acid in dry diethyl ether at −116 °C: Structure IR and Raman spectra suggest that beryllium azide consists of infinite chains, with tetrahedrally coordinated ions linked by end-on bridging ions.
