Thallium azide, Template:Chem2, is a yellow-brown crystalline solid poorly soluble in water. Although it is not nearly as sensitive to shock or friction as lead azide, it can easily be detonated by a flame or spark. It can be stored safely dry in a closed non-metallic container.

Preparation and structure

Thallium azide can be prepared treating an aqueous solution of thallium(I) sulfate with sodium azide. Thallium azide will precipitate; the yield can be maximized by cooling.

Template:Chem2, Template:Chem2, Template:Chem2, and Template:Chem2 adopt the same structures. The azide is bound to eight cations in an eclipsed orientation. The cations are bound to eight terminal N centers.[1]

Safety

All thallium compounds are poisonous and should be handled with care. Azide salts are also roughly as toxic as their corresponding cyanide salts.[2]
