Materials Data on Lu3Ga by Materials Project
Lu3Ga 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 Ga atoms to form distorted LuLu8Ga4 cuboctahedra that share corners with four equivalent GaLu12 cuboctahedra, corners with fourteen equivalent LuLu8Ga4 cuboctahedra, edges with six equivalent GaLu12 cuboctahedra, edges with twelve equivalent LuLu8Ga4 cuboctahedra, faces with four equivalent GaLu12 cuboctahedra, and faces with sixteen equivalent LuLu8Ga4 cuboctahedra. There are a spread of Lu–Lu bond distances ranging from 3.20–3.41 Å. There are two shorter (3.20 Å) and two longer (3.30 Å) Lu–Ga bond lengths. Ga is bonded to twelve equivalent Lu atoms to form GaLu12 cuboctahedra that share corners with six equivalent GaLu12 cuboctahedra, corners with twelve equivalent LuLu8Ga4 cuboctahedra, edges with eighteen equivalent LuLu8Ga4 cuboctahedra, faces with eight equivalent GaLu12 cuboctahedra, and faces with twelve equivalent LuLu8Ga4 cuboctahedra.
