Strontium azide is an inorganic chemical compound with the formula Sr(N₃)₂. It is composed of the strontium cation (Sr²⁺) and the azide anions (N−3).^[1]

Properties

Strontium azide crystallizes in an orthorhombic Fddd space group.^[2] Unlike the azides of alkali metals which have a linear azide ion formation, strontium azide possesses bent azide ions, which can continue to bend further when under higher pressure.^[3]
