Lead styphnate

[3] Samples of lead styphnate vary in color from yellow to gold, orange, reddish-brown, to brown.

As with other lead-containing compounds, lead styphnate is toxic owing to heavy metal poisoning.

[6][3] Normal lead styphnate exists as α and β polymorphs, both being monoclinic crystals.

The styphnate ions lie in approximately parallel planes linked by Pb atoms.

[10] Lead styphnate is mainly used in small arms ammunition for military and commercial applications.

NFPA 704 four-colored diamond Health 4: Very short exposure could cause death or major residual injury. E.g. VX gas Flammability 0: Will not burn. E.g. water Instability 3: Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked. E.g. hydrogen peroxide Special hazards (white): no code
