Lead (Iv) Nitride
Unfortunately, lead (IV) nitride does not exist as a stable compound. Lead can form compounds with nitrogen, but the highest oxidation state for lead in these compounds is +2, not +4.
Lead (II) nitride, also known as lead nitride, has the chemical formula Pb3N2 and is a dark grey or black crystalline solid. It is highly toxic and can release toxic gases upon decomposition. It is primarily used in research and development of electronic and optoelectronic materials.
It is important to note that lead and its compounds are highly toxic and should be handled with caution. In many countries, their use is heavily regulated or banned altogether due to their harmful effects on human health and the environment.
