Y3Bi is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Y(1) is bonded to eight equivalent Y(1) and four equivalent Bi(1) atoms to form distorted YY8Bi4 cuboctahedra that share corners with twelve equivalent Y(1)Y8Bi4 cuboctahedra, edges with eight equivalent Bi(1)Y12 cuboctahedra, edges with sixteen equivalent Y(1)Y8Bi4 cuboctahedra, faces with four equivalent Bi(1)Y12 cuboctahedra, and faces with fourteen equivalent Y(1)Y8Bi4 cuboctahedra. Bi(1) is bonded to twelve equivalent Y(1) atoms to form BiY12 cuboctahedra that share corners with twelve equivalent Bi(1)Y12 cuboctahedra, edges with twenty-four equivalent Y(1)Y8Bi4 cuboctahedra, faces with six equivalent Bi(1)Y12 cuboctahedra, and faces with twelve equivalent Y(1)Y8Bi4 cuboctahedra.
