Protactinium nitride is a binary inorganic compound of protactinium and nitrogen with the chemical formula PaN. [1] [2] [3]
The compound can be obtained from the reaction of protactinium metal and nitrogen: [4]
Also by heating protactinium tetrachloride or pentachloride in ammonia gas. [5]
PaN crystals are of the cubic system with Fm3m space group. [6]
