Infobox references

Lithium antimonide is a binary inorganic compound of lithium and antimony with the molecular formula Li3Sb.

Synthesis

The compound is synthesized by fusing pure elements at 500 °С and high pressure:[1]

3Li + Sb → Li3Sb

When a mixture of lithium and antimony is heated, the elements react violently, releasing intense heat and flame.[2] Other reactions are also known.[3]

Physical properties

The compound forms dark grey cystals of the cubic crystal system, space group Pm3m. At a temperature of 650 °C, a transition to the hexagonal phase occurs, spatial group P63/mmc.[4][5]

Chemical properties

Lithium antimonide reacts with water, producing stibine and lithium hydroxide:

Li3Sb + 3H2O → H3Sb + 3LiOH

Uses

The compound is recognized as a material for lithium batteries and thermoelectric applications.[6]
