Title: Materials Data on Ce4(ErS2)11 by Materials Project

Abstract

Ce4(ErS2)11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Er sites. In the first Er site, Er is bonded to six S atoms to form a mixture of corner and edge-sharing ErS6 octahedra. The corner-sharing octahedra tilt angles range from 48–59°. There are a spread of Er–S bond distances ranging from 2.63–2.78 Å. In the second Er site, Er is bonded to six S atoms to form a mixture of corner and edge-sharing ErS6 octahedra. The corner-sharing octahedra tilt angles range from 48–59°. There are a spread of Er–S bond distances ranging from 2.64–2.77 Å. In the third Er site, Er is bonded to six S atoms to form ErS6 octahedra that share corners with three equivalent ErS6 octahedra, a cornercorner with one ErS7 pentagonal bipyramid, edges with four equivalent ErS6 octahedra, and edges with two equivalent ErS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 50–63°. There are a spread of Er–S bond distances ranging from 2.66–2.76 Å.
