Dy Dy Dy Er
ErDy3 is Uranium Silicide structured and crystallizes in the trigonal R3m space group. Er(1) is bonded to twelve equivalent Dy(1) atoms to form ErDy12 cuboctahedra that share corners with twelve equivalent Er(1)Dy12 cuboctahedra, edges with twenty-four equivalent Dy(1)Dy8Er4 cuboctahedra, faces with six equivalent Er(1)Dy12 cuboctahedra, and faces with twelve equivalent Dy(1)Dy8Er4 cuboctahedra. There are a spread of Er(1)-Dy(1) bond distances ranging from 3.50-3.56 Å. Dy(1) is bonded to four equivalent Er(1) and eight equivalent Dy(1) atoms to form DyDy8Er4 cuboctahedra that share corners with twelve equivalent Dy(1)Dy8Er4 cuboctahedra, edges with eight equivalent Er(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Er4 cuboctahedra, faces with four equivalent Er(1)Dy12 cuboctahedra, and faces with fourteen equivalent Dy(1)Dy8Er4 cuboctahedra. There are a spread of Dy(1)-Dy(1) bond distances ranging from 3.50-3.56 Å.
