Materials Data on SmLu3 by Materials Project
Lu3Sm 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 Sm atoms to form LuSm4Lu8 cuboctahedra that share corners with four equivalent SmLu12 cuboctahedra, corners with fourteen equivalent LuSm4Lu8 cuboctahedra, edges with six equivalent SmLu12 cuboctahedra, edges with twelve equivalent LuSm4Lu8 cuboctahedra, faces with four equivalent SmLu12 cuboctahedra, and faces with sixteen equivalent LuSm4Lu8 cuboctahedra. There are a spread of Lu–Lu bond distances ranging from 3.45–3.60 Å. There are two shorter (3.48 Å) and two longer (3.56 Å) Lu–Sm bond lengths. Sm is bonded to twelve equivalent Lu atoms to form SmLu12 cuboctahedra that share corners with six equivalent SmLu12 cuboctahedra, corners with twelve equivalent LuSm4Lu8 cuboctahedra, edges with eighteen equivalent LuSm4Lu8 cuboctahedra, faces with eight equivalent SmLu12 cuboctahedra, and faces with twelve equivalent LuSm4Lu8 cuboctahedra.
