Title: Materials Data on Er2S3 by Materials Project

Abstract

Er2S3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are six inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to seven S2- atoms to form distorted ErS7 pentagonal bipyramids that share corners with five ErS6 octahedra, edges with four ErS6 octahedra, edges with four equivalent ErS7 pentagonal bipyramids, and a faceface with one ErS6 octahedra. The corner-sharing octahedra tilt angles range from 32–49°. There are a spread of Er–S bond distances ranging from 2.67–2.91 Å. In the second Er3+ site, Er3+ is bonded to seven S2- atoms to form distorted ErS7 pentagonal bipyramids that share corners with three ErS6 octahedra, corners with two equivalent ErS7 pentagonal bipyramids, edges with two equivalent ErS6 octahedra, edges with six ErS7 pentagonal bipyramids, and a faceface with one ErS7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 49–51°. There are a spread of Er–S bond distances ranging from 2.70–2.94 Å. In the third Er3+ site, Er3+ is bonded to seven S2- atoms to form distorted ErS7 pentagonal bipyramids that share corners with two ErS6 octahedra, corners with two equivalent ErS7 pentagonal bipyramids, edges with two equivalent ErS6 octahedra, edges with six ErS7 pentagonal bipyramids, and amore » faceface with one ErS7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 33–34°. There are a spread of Er–S bond distances ranging from 2.71–2.93 Å.
