Rubidium nitride, Rb₃N

The Rubidium nitride, Rb₃N, is formed along with the amide by heating the hydride in nitrogen. The amide is also produced by the action of ammonia on the metal at 200° to 300° C., as well as at lower temperatures. The amide is a white, deliquescent, crystalline substance, melting at 285° to 287° C., and boiling about 400° C.
