The structure described by Al3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Y(1) is bonded to twelve equivalent Al(1) atoms to form YAl12 cuboctahedra that share corners with twelve equivalent Y(1)Al12 cuboctahedra, edges with twenty-four equivalent Al(1)Y4Al8 cuboctahedra, faces with six equivalent Y(1)Al12 cuboctahedra, and faces with twelve equivalent Al(1)Y4Al8 cuboctahedra. Al(1) is bonded to four equivalent Y(1) and eight equivalent Al(1) atoms to form distorted AlY4Al8 cuboctahedra that share corners with twelve equivalent Al(1)Y4Al8 cuboctahedra, edges with eight equivalent Y(1)Al12 cuboctahedra, edges with sixteen equivalent Al(1)Y4Al8 cuboctahedra, faces with four equivalent Y(1)Al12 cuboctahedra, and faces with fourteen equivalent Al(1)Y4Al8 cuboctahedra. is represented by the CIF card [CIF]
