The crystal structure described by Dy3Y is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc 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 four equivalent Y(1)Dy12 cuboctahedra, corners with fourteen equivalent Dy(1)Dy8Y4 cuboctahedra, edges with six equivalent Y(1)Dy12 cuboctahedra, edges with twelve equivalent Dy(1)Dy8Y4 cuboctahedra, faces with four equivalent Y(1)Dy12 cuboctahedra, and faces with sixteen equivalent Dy(1)Dy8Y4 cuboctahedra. Y(1) is bonded to twelve equivalent Dy(1) atoms to form YDy12 cuboctahedra that share corners with six equivalent Y(1)Dy12 cuboctahedra, corners with twelve equivalent Dy(1)Dy8Y4 cuboctahedra, edges with eighteen equivalent Dy(1)Dy8Y4 cuboctahedra, faces with eight equivalent Y(1)Dy12 cuboctahedra, and faces with twelve equivalent Dy(1)Dy8Y4 cuboctahedra. is represented by the CIF card [CIF]
