Rubidium amide nitride

Rubidium nitride, Rb3N, and rubidamide, RbNH2.—The nitride is formed along with the amide by heating the hydride in nitrogen.9 The amide is also produced by the action of ammonia on the metal at 200° to 300° C.,10 as well as at lower temperatures.11 The amide is a white, deliquescent, crystalline substance, melting at 285° to 287° C., and boiling about 400° C. 

Rubidium forms no binary nitride. Like potassium, its amide forms with the cubic rocksalt structure (above 40 C) which distorts to monoclinic symmetry as it is cooled [88, 95], Its azide forms with the KHF, structure, analogous to NaN3 and KN, [77, 85],...
