Title: Materials Data on Tb9Al5S21 by Materials Project

Abstract

Tb9Al5S21 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are six inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to seven S2- atoms to form distorted TbS7 pentagonal bipyramids that share a cornercorner with one AlS6 octahedra, corners with four TbS7 pentagonal bipyramids, corners with two AlS4 tetrahedra, edges with two TbS7 pentagonal bipyramids, an edgeedge with one AlS4 tetrahedra, and a faceface with one AlS6 octahedra. The corner-sharing octahedral tilt angles are 21°. There are a spread of Tb–S bond distances ranging from 2.77–2.92 Å. In the second Tb3+ site, Tb3+ is bonded in a 7-coordinate geometry to eight S2- atoms. There are a spread of Tb–S bond distances ranging from 2.75–3.34 Å.
