Materials Data on TmLu3 by Materials Project
Lu3Tm is Magnesium-derived 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 Tm atoms to form LuTm4Lu8 cuboctahedra that share corners with four equivalent TmLu12 cuboctahedra, corners with fourteen equivalent LuTm4Lu8 cuboctahedra, edges with six equivalent TmLu12 cuboctahedra, edges with twelve equivalent LuTm4Lu8 cuboctahedra, faces with four equivalent TmLu12 cuboctahedra, and faces with sixteen equivalent LuTm4Lu8 cuboctahedra. There are a spread of Lu–Lu bond distances ranging from 3.42–3.53 Å. There are two shorter (3.43 Å) and two longer (3.52 Å) Lu–Tm bond lengths. Tm is bonded to twelve equivalent Lu atoms to form TmLu12 cuboctahedra that share corners with six equivalent TmLu12 cuboctahedra, corners with twelve equivalent LuTm4Lu8 cuboctahedra, edges with eighteen equivalent LuTm4Lu8 cuboctahedra, faces with eight equivalent TmLu12 cuboctahedra, and faces with twelve equivalent LuTm4Lu8 cuboctahedra.
