Li Mg Au Au
LiMgAu2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LiMgAu2 cluster. Li(1) is bonded in a 2-coordinate geometry to one Mg(1) and one Au(2) atom. The Li(1)-Mg(1) bond length is 0.69 Å. The Li(1)-Au(2) bond length is 0.69 Å. Mg(1) is bonded in a single-bond geometry to one Li(1), one Au(1), and one Au(2) atom. The Mg(1)-Au(1) bond length is 0.65 Å. The Mg(1)-Au(2) bond length is 0.04 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted single-bond geometry to one Mg(1) atom. In the second Au site, Au(2) is bonded in a single-bond geometry to one Li(1) and one Mg(1) atom.
