Lithium barium arsenide, Li₄Ba₃As₄, containing isolated As^3- and As₂^4- anions

Li₄Ba₃As₄ (Immm) is isostructural with Li₄Sr₃Sb₄ and Li₄Ba₃Sb₄. It contains two anionic moieties, namely As₂^4- dumbbells and As^3-, and consists of planes of BaAs₆ octahedra separated by corrugated sheets of Li and Ba atoms.
