Materials Data on YEr by Materials Project
ErY is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Er is bonded to six equivalent Er and six equivalent Y atoms to form ErY6Er6 cuboctahedra that share corners with eighteen equivalent ErY6Er6 cuboctahedra, edges with six equivalent ErY6Er6 cuboctahedra, edges with twelve equivalent YY6Er6 cuboctahedra, faces with eight equivalent ErY6Er6 cuboctahedra, and faces with twelve equivalent YY6Er6 cuboctahedra. All Er–Er bond lengths are 3.59 Å. All Er–Y bond lengths are 3.54 Å. Y is bonded to six equivalent Er and six equivalent Y atoms to form YY6Er6 cuboctahedra that share corners with eighteen equivalent YY6Er6 cuboctahedra, edges with six equivalent YY6Er6 cuboctahedra, edges with twelve equivalent ErY6Er6 cuboctahedra, faces with eight equivalent YY6Er6 cuboctahedra, and faces with twelve equivalent ErY6Er6 cuboctahedra. All Y–Y bond lengths are 3.59 Å.
