Materials Data on Yb3Eu by Materials Project

Abstract

Yb3Eu crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded to eight Yb and four equivalent Eu atoms to form YbYb8Eu4 cuboctahedra that share corners with twelve equivalent YbYb8Eu4 cuboctahedra, edges with eight equivalent EuYb12 cuboctahedra, edges with sixteen YbYb8Eu4 cuboctahedra, faces with four equivalent EuYb12 cuboctahedra, and faces with fourteen YbYb8Eu4 cuboctahedra. All Yb–Yb bond lengths are 3.89 Å. All Yb–Eu bond lengths are 3.89 Å. In the second Yb site, Yb is bonded to eight equivalent Yb and four equivalent Eu atoms to form YbYb8Eu4 cuboctahedra that share corners with four equivalent YbYb8Eu4 cuboctahedra, corners with eight equivalent EuYb12 cuboctahedra, edges with twenty-four YbYb8Eu4 cuboctahedra, faces with six equivalent EuYb12 cuboctahedra, and faces with twelve YbYb8Eu4 cuboctahedra. All Yb–Eu bond lengths are 3.89 Å. Eu is bonded to twelve Yb atoms to form EuYb12 cuboctahedra that share corners with four equivalent EuYb12 cuboctahedra, corners with eight equivalent YbYb8Eu4 cuboctahedra, edges with eight equivalent EuYb12 cuboctahedra, edges with sixteen equivalent YbYb8Eu4 cuboctahedra, faces with four equivalent EuYb12 cuboctahedra, and faces with fourteen YbYb8Eu4 cuboctahedra.
