Synthesis

Reaction of promethium and nitric acid:

Pm + 6 HNO3 → Pm(NO3)3 + 3 NO2 + 3 H2O

Physical properties

Promethium(III) nitrate hydrate forms a purple-pink solid. [2] [3]

It forms crystalline hydrates of the composition Pm(NO3)3·6H2O. [4]

Chemical properties

Promethium(III) nitrate thermally decomposes to form promethium(III) oxide. [5]
