Title: Materials Data on La4(HoS2)11 by Materials Project

Abstract

La4(HoS2)11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to seven S2- atoms to form distorted HoS7 pentagonal bipyramids that share corners with three HoS6 octahedra, edges with two equivalent HoS6 octahedra, and edges with four equivalent HoS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 40–50°. There are a spread of Ho–S bond distances ranging from 2.70–2.89 Å. In the second Ho3+ site, Ho3+ is bonded to six S2- atoms to form a mixture of corner and edge-sharing HoS6 octahedra. The corner-sharing octahedra tilt angles range from 49–59°. There are a spread of Ho–S bond distances ranging from 2.65–2.78 Å. In the third Ho3+ site, Ho3+ is bonded to six S2- atoms to form HoS6 octahedra that share corners with three equivalent HoS6 octahedra, corners with two equivalent HoS7 pentagonal bipyramids, and edges with four HoS6 octahedra. The corner-sharing octahedra tilt angles range from 51–63°. There are a spread of Ho–S bond distances ranging from 2.66–2.80 Å. In the fourth Ho3+ site, Ho3+ is bonded to six S2- atoms to form HoS6 octahedra that share corners with three equivalent HoS6 octahedra,more » a cornercorner with one HoS7 pentagonal bipyramid, edges with four equivalent HoS6 octahedra, and edges with two equivalent HoS7 pentagonal bipyramids.
