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.[1] It can also be produced by heating the elements.[2]

3 Li + As → Li3As
