Caesium azide or cesium azide is an inorganic compound of caesium and nitrogen. It is a salt of azide with the formula Шаблон:Chem2.

Structure

Шаблон:Chem2 adopts the same structure as [[potassium azide|Шаблон:Chem2]], [[rubidium azide|Шаблон:Chem2]], and [[thallium azide|Шаблон:Chem2]], crystallizing in a tetragonal distorted caesium chloride structure where each azide ion coordinates to eight metal cations, and each metal cation coordinates to eight terminal N centers.[1] When heated to 151Шаблон:Nbsp°C, it transitions to a cubic structure.[2]

Preparation and reactions

Caesium azide can be prepared from the neutralization reaction between hydrazoic acid and caesium hydroxide:[3]
