Dy3Y is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Dy(1) is bonded to eight equivalent Dy(1) and four equivalent Y(1) atoms to form DyDy8Y4 cuboctahedra that share corners with twelve equivalent Dy(1)Dy8Y4 cuboctahedra, edges with eight equivalent Y(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Y4 cuboctahedra, faces with four equivalent Y(1)Dy12 cuboctahedra, and faces with fourteen equivalent Dy(1)Dy8Y4 cuboctahedra. Y(1) is bonded to twelve equivalent Dy(1) atoms to form YDy12 cuboctahedra that share corners with twelve equivalent Y(1)Dy12 cuboctahedra, edges with twenty-four equivalent Dy(1)Dy8Y4 cuboctahedra, faces with six equivalent Y(1)Dy12 cuboctahedra, and faces with twelve equivalent Dy(1)Dy8Y4 cuboctahedra.
