Strontium azide explained

Strontium azide is an inorganic chemical compound with the formula . It is composed of the strontium cation and the azide anions .^[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]
