Materials Data on Lu3Tl by Materials Project
Lu3Tl is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu is bonded to eight equivalent Lu and four equivalent Tl atoms to form LuLu8Tl4 cuboctahedra that share corners with four equivalent TlLu12 cuboctahedra, corners with fourteen equivalent LuLu8Tl4 cuboctahedra, edges with six equivalent TlLu12 cuboctahedra, edges with twelve equivalent LuLu8Tl4 cuboctahedra, faces with four equivalent TlLu12 cuboctahedra, and faces with sixteen equivalent LuLu8Tl4 cuboctahedra. There are a spread of Lu–Lu bond distances ranging from 3.35–3.40 Å. There are two shorter (3.37 Å) and two longer (3.38 Å) Lu–Tl bond lengths. Tl is bonded to twelve equivalent Lu atoms to form TlLu12 cuboctahedra that share corners with six equivalent TlLu12 cuboctahedra, corners with twelve equivalent LuLu8Tl4 cuboctahedra, edges with eighteen equivalent LuLu8Tl4 cuboctahedra, faces with eight equivalent TlLu12 cuboctahedra, and faces with twelve equivalent LuLu8Tl4 cuboctahedra.
