Materials Data on Yb3Zr by Materials Project

Abstract

Yb3Zr is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb is bonded to eight equivalent Yb and four equivalent Zr atoms to form distorted YbYb8Zr4 cuboctahedra that share corners with four equivalent ZrYb12 cuboctahedra, corners with fourteen equivalent YbYb8Zr4 cuboctahedra, edges with six equivalent ZrYb12 cuboctahedra, edges with twelve equivalent YbYb8Zr4 cuboctahedra, faces with four equivalent ZrYb12 cuboctahedra, and faces with sixteen equivalent YbYb8Zr4 cuboctahedra. There are a spread of Yb–Yb bond distances ranging from 3.48–3.80 Å. There are two shorter (3.53 Å) and two longer (3.64 Å) Yb–Zr bond lengths. Zr is bonded to twelve equivalent Yb atoms to form ZrYb12 cuboctahedra that share corners with six equivalent ZrYb12 cuboctahedra, corners with twelve equivalent YbYb8Zr4 cuboctahedra, edges with eighteen equivalent YbYb8Zr4 cuboctahedra, faces with eight equivalent ZrYb12 cuboctahedra, and faces with twelve equivalent YbYb8Zr4 cuboctahedra.
