Strontium azideStrontium azide is an inorganic chemical compound with the formula. It is composed of the strontium cation and the azide anions.PropertiesStrontium azide crystallizes in an orthorhombic Fddd space group. 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.
