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.
Praseodymium(III) nitride can be prepared by the reaction of nitrogen and metallic praseodymium on heating:
It can also be prepared from the reaction of ammonia and praseodymium metal on heating:
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.
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]
