Y3Al 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 Al(1) atoms to form YY8Al4 cuboctahedra that share corners with twelve equivalent Y(1)Y8Al4 cuboctahedra, edges with eight equivalent Al(1)Y12 cuboctahedra, edges with sixteen equivalent Y(1)Y8Al4 cuboctahedra, faces with four equivalent Al(1)Y12 cuboctahedra, and faces with fourteen equivalent Y(1)Y8Al4 cuboctahedra. Al(1) is bonded to twelve equivalent Y(1) atoms to form AlY12 cuboctahedra that share corners with twelve equivalent Al(1)Y12 cuboctahedra, edges with twenty-four equivalent Y(1)Y8Al4 cuboctahedra, faces with six equivalent Al(1)Y12 cuboctahedra, and faces with twelve equivalent Y(1)Y8Al4 cuboctahedra.
