Title: Materials Data on Yb4PbS8 by Materials Project

Abstract

Yb4PbS8 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are eight inequivalent Yb3+ sites. In the first Yb3+ site, Yb3+ is bonded to eight S2- atoms to form distorted YbS8 hexagonal bipyramids that share corners with two equivalent YbS6 octahedra, edges with two equivalent YbS8 hexagonal bipyramids, and a faceface with one YbS6 octahedra. The corner-sharing octahedral tilt angles are 30°. There are a spread of Yb–S bond distances ranging from 2.58–3.22 Å. In the second Yb3+ site, Yb3+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Yb–S bond distances ranging from 2.77–2.95 Å. In the third Yb3+ site, Yb3+ is bonded to six S2- atoms to form YbS6 octahedra that share corners with two equivalent YbS8 hexagonal bipyramids, corners with two equivalent YbS6 octahedra, and a faceface with one YbS8 hexagonal bipyramid. The corner-sharing octahedral tilt angles are 65°. There are a spread of Yb–S bond distances ranging from 2.64–2.92 Å. In the fourth Yb3+ site, Yb3+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Yb–S bond distances ranging from 2.71–2.95 Å. In the fifth Yb3+ site, Yb3+ is bonded inmore » a 6-coordinate geometry to six S2- atoms. There are a spread of Yb–S bond distances ranging from 2.78–2.99 Å.

In the eleventh S2- site, S2- is bonded in a 4-coordinate geometry to four Yb3+ and two S2- atoms. The S–S bond length is 2.51 Å. In the twelfth S2- site, S2- is bonded in a 4-coordinate geometry to two equivalent Yb3+ and two equivalent S2- atoms.
