Used as nitriding agents, the reducing agent in organic reactions and the nitrogen source inorganic reactions.

The Lithium nitride, with the CAS registry number 26134-62-3, is also known as Nitrure de lithium. It belongs to the product categories of Alternative Energy;Ceramics;Materials for Hydrogen Storage;Nitrides.This chemical's molecular formula is Li₃N and molecular weight is 34.83. What's more,Its systematic name is Lithium nitride.It is a reddish brown powder,Insoluble in most organic solvents.It can be used in metallurgy and chemical synthesis,and used as nitriding agents, the reducing agent in organic reactions and the nitrogen source inorganic reactions,also used as a strong reducing agent in organic synthesis and a solid electrolyte in lithium batteries.

Physical properties about Lithium nitride are:
(1)#H bond acceptors: 1; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 3.;(4)mp: 845°C; (5)density: 1.3 g/mL at 25 °C(lit.);

preparation of Lithium nitride:
It can be formed by direct reaction of the elements, either by burning lithium metal in pure nitrogen gas or by reacting nitrogen gas with lithium dissolved in liquid sodium metal. The second method gives a purer product. Lithium nitride(26134-62-3) reacts violently with water to produce ammonia:
Li3N (s) + 3 H2O (l) → 3 LiOH (aq) + NH3 (g)
Other alkali and alkaline earth nitrides also react in this manner, due to the high basicity of the nitride. The hypothetical nitride ion, N3?, would be an extremely strong Br?nsted base, easily qualifying as a superbase. It is, in fact, a stronger base than the hydride ion, and so deprotonates hydrogen itself:
Li3N (s) + 2 H2 (g) → LiNH2 (s) + 2 LiH (s)
Lithium nitride)is being investigated as a potential storage medium for hydrogen gas, as the reaction is reversible at 270 °C. Up to 11.5% by weight absorption of hydrogen has been achieved.

Safety Information of Lithium nitride:
Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.A powerful reducing agent. Upon contact with moisture, it decomposes into lithium hydroxide, lithium compounds, and ammonia. The powder may ignite spontaneously in moist air. Flammable at elevated temperatures; ignites and burns intensely in air. Violent reaction with silicon tetrafluoride, copper(I) chloride + heat. To fight fire, use dry chemical, sand, graphite; avoid use of water or carbon tetrachloride. When heated to decomposition it emits very toxic fumes of Li2O and NOx.
