Chemical compound

Protactinium nitride is a binary inorganic compound of protactinium and nitrogen with the chemical formula PaN.^[1]^[2]^[3]

Synthesis

The compound can be obtained from the reaction of protactinium metal and nitrogen:^[4]

2Pa + N₂ → 2PaN

Also by heating protactinium tetrachloride or pentachloride in ammonia gas.^[5]

Physical properties

PaN crystals are of cubic system with Fm3m space group.^[6]
