Useful:

• Canonical SMILES: [N-]=[N+]=N[Pb]N=[N+]=[N-]
• Uses: Lead azide [Pb(N3)2] is very unstable and must be handled with care. It is used as a detonator of explosives. As primer in explosives. In the form of dextrinated lead azide. Lead azide is used as a primary explosive indetonators and fuses to initiate the boosteror bursting charge. Generally, it is used indextrinated form. Lead azide is also used inshells, cartridges, and percussion caps.
• Description: Lead azide is a severe explosion risk and should be handled under water; it is also a primary detonating compound.
