Materials Data on Yb3Er by Materials Project
Yb3Er is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to eight equivalent Yb and four equivalent Er atoms to form YbYb8Er4 cuboctahedra that share corners with four equivalent ErYb12 cuboctahedra, corners with fourteen equivalent YbYb8Er4 cuboctahedra, edges with six equivalent ErYb12 cuboctahedra, edges with twelve equivalent YbYb8Er4 cuboctahedra, faces with four equivalent ErYb12 cuboctahedra, and faces with sixteen equivalent YbYb8Er4 cuboctahedra. There are a spread of Yb–Yb bond distances ranging from 3.65–3.83 Å. There are two shorter (3.69 Å) and two longer (3.74 Å) Yb–Er bond lengths. Er is bonded to twelve equivalent Yb atoms to form ErYb12 cuboctahedra that share corners with six equivalent ErYb12 cuboctahedra, corners with twelve equivalent YbYb8Er4 cuboctahedra, edges with eighteen equivalent YbYb8Er4 cuboctahedra, faces with eight equivalent ErYb12 cuboctahedra, and faces with twelve equivalent YbYb8Er4 cuboctahedra.
