Abstract

Yb14AlSb11 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. there are four inequivalent Yb+2.14+ sites. In the first Yb+2.14+ site, Yb+2.14+ is bonded to six Sb3- atoms to form YbSb6 octahedra that share corners with four YbSb6 octahedra, corners with three equivalent YbSb6 pentagonal pyramids, corners with two equivalent AlSb4 tetrahedra, edges with two equivalent YbSb6 octahedra, edges with three equivalent YbSb6 pentagonal pyramids, faces with two YbSb6 octahedra, and a faceface with one YbSb6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 37–55°. There are a spread of Yb–Sb bond distances ranging from 3.20–3.26 Å. In the second Yb+2.14+ site, Yb+2.14+ is bonded to six Sb3- atoms to form YbSb6 octahedra that share corners with eight YbSb6 octahedra, corners with two equivalent YbSb6 pentagonal pyramids, corners with two equivalent AlSb4 tetrahedra, faces with two equivalent YbSb6 octahedra, and faces with four equivalent YbSb6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 39–55°. There are a spread of Yb–Sb bond distances ranging from 3.13–3.38 Å. In the third Yb+2.14+ site, Yb+2.14+ is bonded to six Sb3- atoms to form distorted YbSb6 pentagonal pyramids that share corners with four YbSb6 octahedra, corners with four equivalent YbSb6more »« less
