Lanthanum nitride is a binary inorganic compound of lanthanum and nitride with the chemical formula LaN.^[1]^[2]

Preparation

Lanthanum nitride can be prepared from the reaction of nitrogen and lanthanum trihydride:

2LaH₃ + N₂ → 2LaN + 3H₂

It can also be prepared from the reaction of ammonia and lanthanum trihydride:^[3]

LaH₃ + NH₃ → LaN + 3H₂

The reaction of nitrogen and lanthanum amalgam can also work:^[4]

2La + N₂ → 2LaN

Lanthanum nitride forms black powder that is insoluble in water.^[1] Their crystals are of the cubic system with the Fm3m space group.^[5]

It is paramagnetic.

Lanthanum nitride reacts with water and moisture from the air:^[6]

LaN + 3H₂O → La(OH)₃ + NH₃

It reacts with acids:

LaN + 4HCl → LaCl₃ + NH₄Cl

LaN is used as a LED material, magnetic material, semiconductor, refractory material, dyes, catalyst.^[7]^[8]
