Materials Data on Y3Lu by Materials Project
LuY3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu is bonded to twelve equivalent Y atoms to form LuY12 cuboctahedra that share corners with six equivalent LuY12 cuboctahedra, corners with twelve equivalent YY8Lu4 cuboctahedra, edges with eighteen equivalent YY8Lu4 cuboctahedra, faces with eight equivalent LuY12 cuboctahedra, and faces with twelve equivalent YY8Lu4 cuboctahedra. There are six shorter (3.51 Å) and six longer (3.62 Å) Lu–Y bond lengths. Y is bonded to four equivalent Lu and eight equivalent Y atoms to form YY8Lu4 cuboctahedra that share corners with four equivalent LuY12 cuboctahedra, corners with fourteen equivalent YY8Lu4 cuboctahedra, edges with six equivalent LuY12 cuboctahedra, edges with twelve equivalent YY8Lu4 cuboctahedra, faces with four equivalent LuY12 cuboctahedra, and faces with sixteen equivalent YY8Lu4 cuboctahedra. There are a spread of Y–Y bond distances ranging from 3.53–3.65 Å.
