Physical Properties
Rubidium amide forms colorless crystals of monoclinic syngony .
At 40 ° C, it passes into the phase of cubic syngony .
In the molten state forms a greenish-brown viscous liquid, which corrodes glass and porcelain.
Upon cooling (-42 ° C), the solution in liquid ammonia forms an adduct of the form RbNH 2 • NH 3 .
With air moisture, it interacts with ignition.
Chemical Properties
- Reacts violently with water:
- The solution in ammonia is slowly oxidized by oxygen :
