Lithium arsenide

Lithium arsenide describes inorganic compounds with the chemical formula LixAs where x can range from about 0.5 to 3. A common derivative is Li3As, which is prepared by the reduction of arsenic with a solution of lithium in ammonia. It can also be produced by heating the elements.
 * 3 Li + As → Li3As

Other lithium arsenides
The arsenic-rich arsenides are often classified as zintl phases.
 * Li3As7 adopts a structure akin to the heptaphosphide.
