non-chembox sections[edit]
Lithium tetraamine, Li(NH3)4, is a weakly metallic electride which has the lowest known melting point of any metal. It lies close to a Mott metal insulator transition
Structure[edit]
Each lithium atom is tetrahedrally coordinated by four NH3 molecules. Body centered cubic crystal structure stable between 82 and 89 K, hexagonal structure stable below 82 K.
Deuterated[edit]
Melts at 89 K Doesn't undergo a phase transition at 82 K. Transition to simple cubic structure at 22 K.
Magnetic properties[edit]
Electrical properties[edit]
Preparation[edit]
Formed from the dissolution of lithium in ammonia at the proper ratio
Reactions[edit]
Powerful reducing agent
