Praseodymium(III) nitride is a binary inorganic compound of praseodymium and nitrogen.[2] Its chemical formula is PrN.[3] The compound forms black crystals, and reacts with water.

Preparation

Praseodymium(III) nitride can be prepared by the reaction of nitrogen and metallic praseodymium on heating:

2 Pr + N2 → 2 PrN

It can also be prepared from the reaction of ammonia and praseodymium metal on heating:

2 Pr + 2 NH3 → 2 PrN + 3 H2

Properties

Praseodymium(III) nitride forms black crystals of a cubic system. The space group is Fm3m,[4] with cell parameter a = 0.5165 nm, Z = 4, its structure similar to that of sodium chloride (NaCl).

The compound is readily hydrolyzed with water and reacts with acids.

Applications

The compound is used in high-end electric and semiconductor products, and as a raw material to produce phosphor. Also it is used as a magnetic material and sputtering target material.[5]
