Americium nitride is a binary inorganic compound of americium and nitride with the chemical formula LaN.[1][2]

Preparation

Reaction of nitrogen and lanthanum trihydride:

2LaH3 + N2 → 2LaN + 3H2

Reaction of ammonia and lanthanum trihydride:[3]

2LaH3 + NH3 → LaN + 3H2

Reaction of nitrogen and lanthanum amalgam:

2La + N2 → LnN

Physical properties

LaN forms black powder, insoluble in water.[1] LaN crystals are of cubic system with Fm3m space group.[4]

Paramagnetic.

Chemical properties

Lanthanum nitride reacts with water and moisture from the air:

LaN + 3H2O → La(OH)3 + NH3

Reacts with acids:

LaN + 4HCl → LaCl3 + NH4Cl

Uses

LaN is used as a LED material, magnetic material, semiconductor, dyes, catalyst.[5][6]
