Materials Data on Dy3Lu by Materials Project

Abstract

LuDy3 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 Dy atoms to form LuDy12 cuboctahedra that share corners with six equivalent LuDy12 cuboctahedra, corners with twelve equivalent DyDy8Lu4 cuboctahedra, edges with eighteen equivalent DyDy8Lu4 cuboctahedra, faces with eight equivalent LuDy12 cuboctahedra, and faces with twelve equivalent DyDy8Lu4 cuboctahedra. There are six shorter (3.50 Å) and six longer (3.59 Å) Lu–Dy bond lengths. Dy is bonded to four equivalent Lu and eight equivalent Dy atoms to form DyDy8Lu4 cuboctahedra that share corners with four equivalent LuDy12 cuboctahedra, corners with fourteen equivalent DyDy8Lu4 cuboctahedra, edges with six equivalent LuDy12 cuboctahedra, edges with twelve equivalent DyDy8Lu4 cuboctahedra, faces with four equivalent LuDy12 cuboctahedra, and faces with sixteen equivalent DyDy8Lu4 cuboctahedra. There are a spread of Dy–Dy bond distances ranging from 3.51–3.61 Å.
