The material structure described by Li3Mg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Li(1) is bonded to eight equivalent Li(1) and four equivalent Mg(1) atoms to form LiLi8Mg4 cuboctahedra that share corners with twelve equivalent Li(1)Li8Mg4 cuboctahedra, edges with eight equivalent Mg(1)Li12 cuboctahedra, edges with sixteen equivalent Li(1)Li8Mg4 cuboctahedra, faces with four equivalent Mg(1)Li12 cuboctahedra, and faces with fourteen equivalent Li(1)Li8Mg4 cuboctahedra. Mg(1) is bonded to twelve equivalent Li(1) atoms to form MgLi12 cuboctahedra that share corners with twelve equivalent Mg(1)Li12 cuboctahedra, edges with twenty-four equivalent Li(1)Li8Mg4 cuboctahedra, faces with six equivalent Mg(1)Li12 cuboctahedra, and faces with twelve equivalent Li(1)Li8Mg4 cuboctahedra. is represented by the CIF file [CIF]
