The compound described by Mg3Bi is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to eight equivalent Mg(1) and four equivalent Bi(1) atoms to form distorted MgMg8Bi4 cuboctahedra that share corners with twelve equivalent Mg(1)Mg8Bi4 cuboctahedra, edges with eight equivalent Bi(1)Mg12 cuboctahedra, edges with sixteen equivalent Mg(1)Mg8Bi4 cuboctahedra, faces with four equivalent Bi(1)Mg12 cuboctahedra, and faces with fourteen equivalent Mg(1)Mg8Bi4 cuboctahedra. Bi(1) is bonded to twelve equivalent Mg(1) atoms to form BiMg12 cuboctahedra that share corners with twelve equivalent Bi(1)Mg12 cuboctahedra, edges with twenty-four equivalent Mg(1)Mg8Bi4 cuboctahedra, faces with six equivalent Bi(1)Mg12 cuboctahedra, and faces with twelve equivalent Mg(1)Mg8Bi4 cuboctahedra. is represented by the CIF card [CIF]
